[Dovecot] Authentication failed, failure to login after changed password

[Vinit Jain]

Hi, 

I have installed dovecot 1.0 mail  server on debian linux.  I am using unix authentication to login the mail accounts.

We developed one web mail application whcih use imap protocol  and send mail fro sending the mail.

We are creating unix user through our application and able to login
to the mail account succesfully and do all opeartion on that.

But once user change password through our application or directly
on unix commaqnd prompt then we are unable to login to mail application
it gives authentication failed error.


Even user can use ssh, sftp after changing password. Everything works except mail account.


Here is the error excerpt from log files (mail.log and auth.log ) respectively.


Aug 26 10:58:37 digibeanz dovecot: imap-login: Aborted login (1
authentication attempts): user=<child2>, method=PLAIN,
rip=127.0.0.1, lip=127.0.0.1, TLS

Please help me. This is very urgent
