email authentication failed

[ManuelJ]

Hi,

I've problems to login to any mailservice (imap, pop, webmail, ...). The server don't accept my password. This problem appears approx one time a day and mostly fixed after reboot.
My idea is a problem with the courier-authdaemon. For example, when I try to login to horde webmail I got these message in /var/log/mail.log:

May 7 14:50:01 plesk6 courier-imapd: Connection, ip=[::ffff:127.0.0.1]
May 7 14:50:01 plesk6 courier-authdaemon: received auth request, service=imap, authtype=login
May 7 14:50:01 plesk6 courier-authdaemon: authpsa: trying this module
May 7 14:50:01 plesk6 courier-authdaemon: authpsa: sysusername=popuser, sysuserid=110, sysgroupid=31, homedir=/var/qmail/mailnames/funtasticsix.de/manuel, [email protected], fullname=<null>, maildir=<null>, quota=<null>, options=<null>
May 7 14:50:01 plesk6 courier-authdaemon: Authenticated: sysusername=popuser, sysuserid=110, sysgroupid=31, homedir=/var/qmail/mailnames/funtasticsix.de/manuel, [email protected], fullname=<null>, maildir=<null>, quota=<null>, options=<null>
May 7 14:50:01 plesk6 courier-authdaemon: authpsa: auth_psa_common() callback returned 0

This indicate that my password is correct because when I try to login with a wrong password the logfile look like this:

May 7 14:52:14 plesk6 courier-imapd: Connection, ip=[::ffff:127.0.0.1]
May 7 14:52:14 plesk6 courier-authdaemon: received auth request, service=imap, authtype=login
May 7 14:52:14 plesk6 courier-authdaemon: authpsa: trying this module
May 7 14:52:14 plesk6 courier-authdaemon: authpsa: password for account '[email protected]' is wrong
May 7 14:52:14 plesk6 courier-authdaemon: authpsa: sysusername=popuser, sysuserid=110, sysgroupid=31, homedir=<null>, address=<null>, fullname=<null>, maildir=<null>, quota=<null>, options=<null>
May 7 14:52:14 plesk6 courier-authdaemon: authpsa: TEMPFAIL - no more modules will be tried
May 7 14:52:14 plesk6 courier-imapd: LOGIN FAILED, method=PLAIN, ip=[::ffff:127.0.0.1]
May 7 14:52:14 plesk6 courier-imapd: authentication error: Input/output error


currently the problem stay also after rebooting many times
Anybody an idea or the same problem?

I'm running Plesk 11.5.30 Update #44 on Ubuntu 12.04.4 LTS

Problem solved.

/var/qmail/mailnames is mounted via NFS and for some reason the time from NFS Server and Plesk Server differs for more than 30sec. and causes a error.
