[Dovecot] dovecot proxying with imapc
by suja 04 Mar '13

04 Mar '13

Dear sir, I have to set up a mail gateway which will be explored to Internet and a secure mail server in the Intranet. I need a smart imap proxy in the mail gateway which will fetch the mail from server and present to user through either a stand alone mail client or a web mail client. All authentication is through ldap server. I followed the instructions given in http://wiki2.dovecot.org/HowTo/ImapcProxy But while logging in I am getting a error: dovecot: imap(user1): Error: user user1:Initialization failed: Initializing mail storage from mail_location setting failed: Unknown mail storage driver imapc dovecot: imap(user1): Error: Invalid user settings. Refer to server log for more information. I couldn't figure out what is wrong. Please help me to sort it out.

Some IMAP clients do sort folders, others do not, so they show different folder sort order in Dovecot, if migrated from Courier (Courier seems to sort folders, so that the system ones appear first). We just needed a seamless migration. >FWIW, this is completely legal IMAP output also (albeit inefficient): > >a list "" * >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "Sent" >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "Drafts" >* LIST (\HasNoChildren) "/" "Trash" >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "Spam" >* LIST (\HasNoChildren) "/" "INBOX" >* LIST (\HasNoChildren) "/" "Pub" >a OK List completed. > So, it is legal to even list each folder several times? >michael WBR, valerius

[Dovecot] No NTLM with PAM after upgrade
by Phil Quesinberry 01 Mar '13

01 Mar '13

After updating From Dovecot 1.07 (included with CentOS 5) to 2.11, NTLM authentication will not work. Attempts to authenticate against Samba version 4.0.4-GIT-20cb7de also fail with 'auth: Info: winbind(?,192.168.2.100): user not authenticated: NT_STATUS_UNSUCCESSFUL', despite the fact that the same user can sign on to the Samba domain and access files. What I'm really trying to understand here though is why version 1.07 would do NTLM with PAM just fine, but later versions I've tried will not. After failing to get later versions to work, I decided to see if I could at least get them to do NTLM by authenticating against a Samba domain but that won't work either. 1.07 did NTLM just fine authenticating against a system user account with PAM, as demonstrated by the following excerpt from the log: dovecot: Feb 06 12:46:59 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:46:59 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:47:42 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 06 12:47:42 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 06 12:48:03 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:48:03 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:48:44 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 06 12:48:44 Info: IMAP(pquesinb): Disconnected: Logged out Authentication settings for 1.07 were as follows (excerpt from -n output, see below for full output): auth default: mechanisms: ntlm plain passdb: driver: passwd-file args: /etc/dovecot.users passdb: driver: pam args: cache_key=%u dovecot userdb: driver: passwd Since 1.07 was such an old version, I first tried updating to 1.2.17 and lost the ability to do NTLM authentication with the same settings: Feb 06 16:09:32 dovecot: Info: Dovecot v1.2.17 starting up (core dumps disabled) Feb 06 16:09:46 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:09:53 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:10:05 imap-login: Info: Disconnected (auth failed, 2 attempts): user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 Feb 06 16:11:54 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:12:04 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:12:16 imap-login: Info: Disconnected (auth failed, 2 attempts): user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 Next I decided to try 2.x and since I had installed 1.2.17 from source, I thought it would be wise to install from an RPM which had been "blessed" for CentOS 5, so 2.1.1 was installed from the RPMs linked to on the Dovecot download site: http://dl.atrpms.net/all/dovecot-2.1.1-2_132.el5.x86_64.rpm Still no NTLM authentication with 2.x using PAM, so I decided to try authenticating against the Samba 4 domain using Samba's winbind daemon and ntlm_auth helper. That still doesn't work however, as seen by the following log excerpt but plaintext login which is also enabled, works: Feb 28 23:29:13 auth: Debug: auth client connected (pid=18518) Feb 28 23:29:13 auth: Debug: client in: AUTH 1 NTLM service=imap lip=192.168.2.102 rip=192.168.2.100 lport=143 rport=4531 Feb 28 23:29:15 auth: Debug: client out: FAIL 1 Feb 28 23:29:15 auth: Debug: client in: AUTH 2 PLAIN service=imap lip=192.168.2.102 rip=192.168.2.100 lport=143 rport=4530 resp=AHBxdWVzaW5iAFN0ZXdCMHkv Feb 28 23:29:17 auth: Debug: client out: CONT 1 Feb 28 23:29:17 auth: Debug: client in: CONT 1 TlRMTVxxxxxxxAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFASgKAAAADw== Feb 28 23:29:17 auth: Error: could not obtain winbind netbios name!
