Authentication lost within session

[Marc Roos]

Hmmm, strange my limits.conf is still default empty. I also reverted 
back to the orginal dovecot pam.d file, and still the same. Is dovecot 
indeed then giving this password mismatch on max logins? 
I have been testing quite a lot lately without noticing this. The only 
thing I can remember changing recently was enabling shmkey of slapd and 
tuning settings in nscd.

Sorry I mistakenly overlooked at the ip:s. But anyway that is multiple 
connections and seems that PAM has some concurrency limit and refuses 
the third connection Thunderbird opens.

so you probably have pam_limits with maxlogins=2 enabled.
