[Dovecot] ldap and digest-md5 problem

Hi, I'm using dovecot-1.0.0 on gentoo box and I have problem with authentication using digest-md5 and passwords stored as plain text in ldap database, when I use cram-md5 it works, while digest-md5 give this error (squirrelmail login): May 5 16:03:32 srv dovecot: auth(default): client in: AUTH 1 DIGEST-MD5 service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 May 5 16:03:32 srv dovecot: auth(default): client out: CONT 1 [password hash] May 5 16:03:32 srv dovecot: auth(default): client in: CONT<hidden> May 5 16:03:32 srv dovecot: auth(default): ldap(user(a)domain.com,127.0.0.1): pass search: base=ou=domain.com,cn=Users,dc=domain,dc=com scope=subtree filter=(&(objectClass=posixAccount)(uid=user)) fields=userPassword May 5 16:03:32 srv dovecot: auth(default): ldap(user(a)domain.com,127.0.0.1): result: userPassword(password)=<hidden> May 5 16:03:32 srv dovecot: auth(default): digest-md5 (user(a)domain.com,127.0.0.1) password mismatch May 5 16:03:32 srv dovecot: auth(default): client out: FAIL 1 user=user(a)domain.com May 5 16:03:32 srv dovecot: imap-login: Aborted login: user=<user(a)domain.com>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, secured It seems that client and dovecot hashes calculated for DIGEST-MD5 are different, I tested squirrelmail 1.4.9a, kmail 3.5.6 both can't login using digest-md5 so maybe dovecot does not working correctly?

[Dovecot] Switching from mailbox to maildir.. duplicates!
by Lars Johansen 09 May '07

09 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Strange Mail Problem
by Jason Baker 09 May '07

09 May '07

I submitted this question to the Postfix maillist and they suggested that I post to this one. Here's my issue: I have a Postifx email system running on a CentOS 4 box, with Dovecot pop3 and imap. Last week, one of my users reported to me that about a dozen emails suddenly showed up in his in box (as unread messages), but none of them were addressed to him. Under further investigation, they turned out to be from another user's inbox. The messages were all over a month old. How could mail simply show up in one inbox from another user's? We're using Mozilla Thunderbird 1.5. Anyone else run into issues like this? -- *Jason Baker */IT Coordinator/ *Glastender Inc.* 5400 North Michigan Road Saginaw, Michigan 48604 USA 800.748.0423 Phone: 989.752.4275 ext. 228 Fax: 989.752.4444 www.glastender.com <http://www.glastender.com> -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT$ d- s: a C++$ LU+++$ P+ L++>L++++ !E--- W+++ N o?

[Dovecot] File Changes and IDLE
by Andy Shellam 09 May '07

09 May '07

Hi Timo and all, I used to use Dovecot back in the 0.99 days a couple of years ago, had since moved to Courier IMAP, but with the release of Dovecot 1.0.0, I'm looking at moving back! One thing I currently have set up and working with Courier is the use of the enhanced IDLE mode, whereby Courier uses FAM (File Alteration Monitor) to monitor changes in the INBOX, and sends the details to the client as soon as a new mail arrives. Is this something that Dovecot supports? If possible, I'd prefer not to use FAM, as it crashes at random intervals and I have to keep restarting it. When I configured Dovecot, it said "File change notification method ..... : none". Does this mean FreeBSD doesn't support any method of notifying of file changes? Is there any way I can install, or re-configure the kernel, to include this support? Thanks, Andy

[Dovecot] auth(default): Error sending status request (Operation not permitted)
by Keith Bjorndahl 09 May '07

09 May '07

After upgrading to dovecot-1.0.0 from dovecot-0.99.14, I've started getting the following errors: auth(default): Error sending status request (Operation not permitted) but yet everything _seems_ to be functioning okay ... so far. This is a FC4 system, SELinux is re-configured and still generates errors with SELinux disabled. Ideas?
