[Dovecot] Dovecot 2.0.x + Sendmail 8.14.4 SMTP AUTH not working
by Serhiy Kolesnyk 31 Jul '11

31 Jul '11

Hello! After moving from Centos 5.6 to Centos 6, I figured that Sendmail minor version was updated from 8.13.x to 8.14 and Dovecto from 1.2 to 2.0.x In previous configuration SMTP auth worked fine (no SASAUTHD neccessary) for virtual users table. Dovecot was authenticating virtual users virtual checking dovecot.passwd file. I'm not sure how Sendmail was processing SMTP AUTH for virtual users connecting via email clients since there was no obvious connection to Dovecot authentication. But SMTP AUTH was working and virtual users could send email via SSL. Now after this recent upgrade I looked into Dovecot conf changes and updated it according. POP/IMAP are working and Sendmail does deliver incoming mail to the mbox folders. What stopped working is SMTP AUTH. Here's maillog excerpt of authentication process: Jul 29 23:46:11 one2action sendmail[2865]: AUTH: available mech=CRAM-MD5 DIGEST-MD5 LOGIN GSSAPI PLAIN, allowed mech=LOGIN PLAIN Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, get_verify: 0 get_peer: 0x0 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, relay=136-31-132-95.pool.ukrtel.net [95.132.31.136], version=TLSv1/SSLv3, verify=NO, cipher=RC4-MD5, bits=128/128 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, cert-subject=, cert-issuer=, verifymsg=ok Jul 29 23:46:11 one2action sendmail[2865]: AUTH: available mech=CRAM-MD5 DIGEST-MD5 LOGIN GSSAPI PLAIN, allowed mech=LOGIN PLAIN Jul 29 23:46:11 one2action sendmail[2865]: p6TMkB95002865: --- 220 one2action.com ESMTP Sendmail 8.14.4/8.14.4; Fri, 29 Jul 2011 23:46:11 +0100 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: <-- EHLO astronaut Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-one2action.com Hello 136-31-132-95.pool.ukrtel.net [95.132.31.136], pleased to meet you Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-ENHANCEDSTATUSCODES Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-PIPELINING Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-8BITMIME Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-SIZE Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-DSN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-ETRN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-AUTH LOGIN PLAIN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-DELIVERBY Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250 HELP Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: <-- AUTH LOGIN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 334 VXNlcm5hbWU6 Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 334 UGFzc3dvcmQ6 Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 535 5.7.0 authentication failed Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: AUTH failure (LOGIN): generic failure (-1) SASL(-1): generic failure: checkpass failed, relay=136-31-132-95.pool.ukrtel.net [95.132.31.136] Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 421 4.4.1 one2action.com Lost input channel from 136-31-132-95.pool.ukrtel.net [95.132.31.136] Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: lost input channel from 136-31-132-95.pool.ukrtel.net [95.132.31.136] to TLSMTA after auth Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: 136-31-132-95.pool.ukrtel.net [95.132.31.136] did not issue MAIL/EXPN/VRFY/ETRN during connection to TLSMTA Here's dovecot -n # dovecot -n # 2.0.beta6 (3156315704ef): /etc/dovecot/dovecot.conf # OS: Linux 2.6.39.1-linode34 i686 CentOS Linux release 6.0 (Final) auth_cache_negative_ttl = 3600 s auth_debug_passwords = yes auth_mechanisms = plain login DIGEST-MD5 cram-md5 auth_worker_max_count = 3 default_client_limit = 10 default_process_limit = 5 disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl passdb { args = scheme=MD5-CRYPT username_format=%u /etc/dovecot/dovecot.passwd driver = passwd-file } passdb { args = dovecot driver = pam } passdb { args = /etc/passwd driver = passwd-file } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = smmsp mode = 0666 user = smmsp } unix_listener dovecot-auth { group = smmsp mode = 0666 user = smmsp } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/pki/tls/certs/sendmail.pem ssl_cipher_list = TLSv1+HIGH:!SSLv2:RC4+MEDIUM:!aNULL:!eNULL:!3DES:@STRENGTH ssl_key = </etc/pki/tls/certs/sendmail.pem userdb { args = username_format=%u /etc/dovecot/dovecot.passwd driver = passwd-file } protocol lda { auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)example.com } protocol imap { imap_client_workarounds = delay-newmail } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } As I understand Sendmail now can't find Dovecot authentication via userdb and that's why a client isn't authenticated.

[Dovecot] lda_mailbox_autosubscribe - v2 wiki is a bit unclear
by Thomas Harold 29 Jul '11

29 Jul '11

In the old wiki: http://wiki1.dovecot.org/LDA -m <mailbox>: Destination mailbox (default is INBOX). If the mailbox doesn't exist, it's created (unless -n is used). If message couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead. -s: Subscribe to mailboxes that are automatically created (via -m parameter or fileinto Sieve action). (v1.1.3+) Those have been replaced in Dovecot v2 with: # Should saving a mail to a nonexistent mailbox automatically create it? lda_mailbox_autocreate = no # Should automatically created mailboxes be also automatically subscribed? lda_mailbox_autosubscribe = no But neither of those options are mentioned on the LDA wiki page: http://wiki2.dovecot.org/LDA It's only mentioned in passing on the 2.0 page that explains the changes between 1.2 and 2.0.

[Dovecot] vpopmail + dovecot-lda doubling deliver messages
by Juliano Nascimento 29 Jul '11

29 Jul '11

We use qmail + vpopmail + dovecot, limits and alias are in vpopmail mysql database, it has worked ok. The .qmail-default: | /data/vpopmail/bin/vdelivermail '' bounce-no-mailbox | /var/qmail/bin/preline -f /usr/local/dovecot/libexec/dovecot/deliver -d $EXT@$USER When you send a message to alias works OK. The problem that is happening that is sent to asdf(a)domain.com asdf(a)domain.com he is doubling the email. Come the email that you sent / wrote an email and more with nearly no head, no matter. Searching is very realized that something related to Deliver the dovecot. Can you help us? Tips? Thank you all.

Hello, I'm using a patched version of passdb-vpopmail.c to use CRAM-MD5 on the director. Today I updated the patch to 2.0.13. It may be an edge-case but I think it could be useful for somebody else. Greetings Martin

[Dovecot] want only usder in userfile/passfile and use to login user@domain
by Erik - versatel 28 Jul '11

28 Jul '11

After adding: auth_username_format=%Lu the %d domain is unfolleded correctly. (and not empty anymore) Maybe a good idee to make a remark in the text Virtual Users about that. I use: passdb: driver: passwd-file args: /etc/dovecot/vhosts/%d/etc/shadow userdb: driver: static args: uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u In the password-file (shadow) i have to add users in the form user@domain. I want to add users in the form user I have also tryed not a static userdb but a real one; see example Dynamic-passwd locations. To get this working i had to add mail-uid and mail-gid. But still it has the same form user@domain and not user Can anybody tell my how to get ride of the domain part in the passwd en userfile. I still want the user to login with user@domain Thanks.

For example when user test have password: Sierpieńłą*123 in log file item appears: localhost dovecot: auth: ldap(test,192.168.0.68): invalid credentials (given password : SierpieDB#005*123) What can I do?

[Dovecot] dovecot quota feature request
by Shing 28 Jul '11

28 Jul '11

Hi all, I'm going to implement before queue quota check with postfix to prevent bounce mail, the quota information is stored into mysql using dovecot quotadict, it would be nice that dovecot can have an option to switch the quota check with (used space < quota) instead of (used space+mail size < quota), so that i can write a simple sql statement to check_recipient_access to reject those mail, thanks.

[Dovecot] Store quota on passwd-file?? Not work
by Sébastien FOURCADE 28 Jul '11

28 Jul '11

Hello all, I have installed Dovecot 1.2.15 and Postfix 2.7.1 on my Debian 6.This install no include MySQL, I prefer to store Password/User in a file... File /etc/dovecot/passwd contains :user2@domain.com:{CRAM-MD5}::::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:bytes=300M File /etc/dovecot/users :user2@domain.com::3000:3000::/home/vmail/domain.com/user2/:/bin/false:: What is the correct syntax for my file to use a different per-user quota ? This example not work on my Dovecot :user2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:storage=200Muser2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_quota_rule=*:bytes=200M Thx.

[Dovecot] set delay between pop3-logins
by tonjg 28 Jul '11

28 Jul '11

I'm using dovecot 1.1.8 on a raq4 server running centos 4.8 Is it possible to set a time delay between all dovecot pop3-logins? say 20 - 30 seconds for example? My reason is I want to thwart the constant login attempts from hackers hunting for an open relay. It's no good blocking the ip address because every hack attempt comes in from a different address. I'm the only user on the server so no-one else would be affected by such a delay. Thanks for any pointers -- View this message in context: http://old.nabble.com/set-delay-between-pop3-logins-tp32134037p32134037.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] lmtp multiple recipients fail
by flylordis flylordis 28 Jul '11

28 Jul '11

Hello, I am having a problem with the lmtp delivery of mail addressed to multiple recipients. The first recipient receives the mail correctly but the next recipients do not. ltmp apparently tries to create a link from the subsequent recipients' mail store to the first recipient mail store and fails. This returns 451 smtp codes to the sender which then resends at some later time. Please see below for users jerry, steve, and mary. The message to jerry gets written but not steve or mary: ul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: none: root=, index=, control=, inbox= Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Connect from 143.112.53.4 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: jerry home=/spool/mail/j/jerry system_groups_user=jerry uid=18738 gid=4025 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: steve home=/spool/mail/s/steve system_groups_user=steve uid=9838 gid=3011 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: mary home=/spool/mail/m/mary system_groups_user=mary uid=7007 gid=3011 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Effective uid=18738, gid=4025, home=/spool/mail/j/jerry Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: fs: root=/spool/mail/j/jerry/mail, index=, control=, inbox=/spool/mail/j/jerry/mail/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900@backup.>: saved mail to INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Effective uid=9838, gid=3011, home=/spool/mail/s/steve Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: fs: root=/spool/mail/s/steve/mail, index=, control=, inbox=/spool/mail/s/steve/mail/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900@backup.>: save failed to INBOX: Internal error occurred.

Hi, I'm using Dovecot 1.2.15 on Debian. On some clients, at least KMail, some messages (especially older ones) appear twice in the message list of the client. This is really annoying. Can anyone give me a hint on how to solve this issue? -- Best Regards, Dominik Schulz

Hello I would be grateful if someone could send an example of a dictionnary flat file used by the shared mailboxes feature, it has very few here so a flat file will be enough I think. Thank you

[Dovecot] Problem with client login in 1.2.17
by John O'Brien 27 Jul '11

27 Jul '11

Hi, I have been using CentOS 5.5 with Dovecot 1.0.7. My client apps login with TLS/SSL using an postgres database for username and password authentication. I developed a plugin that added an additional IMAP command. I want to eventually migrate to release 2.0 but have decided to make this a two step process. I have started with 1.2.17 as I hope this would be a smaller step along the way. I have installed 1.2.17 from source an installed. Rebuilt my plugin and installed and set about updating the dovecot.conf file. Installing the SSL certificate etc.....

[Dovecot] sieve, vacation - lda-dupes being ignored?

Environment: dovecot 2.0.9, postfix 2.6, Pigeonhole 0.2.2 I'm in the process of setting up vacation auto-reply for the first time, (it's that time of the year) and it looks like .dovecot.lda-dupes is being updated, but not read (or just ignored). my vacation script: require ["vacation","variables"]; # get hold of the subject if header :matches "Subject" "*" { set "subj" "${1}"; } vacation # Reply at most once a week to a same sender :days 7 :subject "Re: ${subj} (automatic reply; I am out of the office)" :addresses "pjessen(a)example.com" :mime text: The script works fine, but I get a reply for every msg sent: # grep sieve.*sent /var/log/mail Jul 26 10:17:26 neon dovecot: lmtp(4367, per.acm(a)example.com) Pj0iEbx3Lk4PEQAA0G3O/A: sieve: msgid=<4E2E7807.8000301(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Jul 26 10:29:06 neon dovecot: lmtp(10165, per.acm(a)example.com) Hbm3DhJ6Lk61JwAA0G3O/A: sieve: msgid=<4E2E7ABF.3090804(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Jul 26 11:09:41 neon dovecot: lmtp(2496, per.acm(a)example.com) WPtRMVWELk7ACQAA0G3O/A: sieve: msgid=<4E2E8447.9070007(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Jul 26 11:32:26 neon dovecot: lmtp(15648, per.acm(a)example.com) 7pQrLKqJLk4gPQAA0G3O/A: sieve: msgid=<4E2E8999.8040800(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Jul 26 11:39:12 neon dovecot: lmtp(18845, per.acm(a)example.com) ds9CDfeKLk6dSQAA0G3O/A: sieve: msgid=<4E2E8B30.1070804(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Jul 26 11:42:40 neon dovecot: lmtp(21484, per.acm(a)example.com) eXZHOw+MLk7sUwAA0G3O/A: sieve: msgid=<4E2E8BF9.7010301(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Jul 26 15:26:25 neon dovecot: lmtp(19216, per.acm(a)example.com) Wma/OIDALk4QSwAA0G3O/A: sieve: msgid=<4E2EC06F.5060307(a)example.com>: sent vacation response to <SRS0+9c3c5bbcdb70e56f=2N=example.com=per.jessen(a)srs.example.org> Is there a way to dump the contents of lda-dupes in clear text? thanks Per Jessen, Zürich

EVERY time the user checks his mails. I haven't heard any user complaint about this, but perhaps nobody tried this before. I recreated this situation (copy old qpopper message INBOX -> tmpbox -> INBOX) and produced two messages with identical X-UIDL headers, but according to the Wikipedia entry for POP3: Comparison with IMAP Clients that leave mail on servers generally use the UIDL command to get the current association of message-numbers to message identified by its unique identifier. The unique identifier is arbitrary, and might be repeated if the mailbox contains identical messages. This is echoed in RFC1939 (page 11-12) While it is generally preferable for server implementations to store arbitrarily assigned unique-ids in the maildrop, this specification is intended to permit unique-ids to be calculated as a hash of the message. Clients should be able to handle a situation where two identical copies of a message in a maildrop have the same unique-id. So POP3 UIDLs are not guaranteed to be unique, especially if the messages are the same. Perhaps some mail readers are making unwarranted assumptions about the uniqueness of UIDLs: http://www.eggheadcafe.com/software/aspnet/33485042/duplicate-messageiduidl… https://www.ritlabs.com/bt/view.php?id=3599 Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] phantom new message notification
by Stan Hoeppner 26 Jul '11

26 Jul '11

I've developed a phantom new message notification on a single IMAP folder in Thunderbird. I've deleted the Dovecot index files for this problematic folder, and I've deleted the .msf file in the Tbird profile. Neither of which solved the problem. The only other time I've run into something similar was with CONDSTORE quite a long time ago, but that affected all folders, not just one. Any ideas? -- Stan

[Dovecot] drac plugin "net_ip2addr() failed: Operation not permitted"
by Michael Moritz 25 Jul '11

25 Jul '11

Hi, I'm trying to get the drac plugin working (again) but I'm stuck with the following message: Restarting IMAP/POP3 mail server: dovecotEDRAC: net_ip2addr() failed: Operation not permitted This is on a Debian Squeeze box, dovecot version 1.2.15-7, drac version 1.12 Looking at the source it should print the IP in the brackets of net_ip2addr. The fact that it's just empty made me think that I may need to set an environment variable. I tried IP="127.0.0.1" in /etc/default/dovecot and as export but to no avail. Any ideas? Thanks, mimo

[Dovecot] passwd not found
by Erik - versatel 25 Jul '11

25 Jul '11

If I use in dovecot.conf passdb passwd-file { args = /etc/dovecot/vhosts/%d/etc/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } I get an authorisation failure in my mail.log file. If I use passdb passwd-file { args = /etc/dovecot/vhosts/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } This works !!! (without the %d) in the passdb passwd-file Than the %d/%u is correctly rewritten in the userdb static. PS I have in the passwd-file the username@domain and the username documented for testing. I think there is some problem with the %d (DOMAIN) How can I check if %d is filled ?? And how can i make different authorisationdirs and files per domain.
