dovecot - May 2007 - May 21 09:13:14 mail dovecot: imap-login: No authentication sockets found

I started getting this message this morning: May 21 09:13:14 mail  
dovecot: imap-login: No authentication sockets found

Ive been runing dovecot on a fc6 dell poweredge 2950 for about 4 weeks  
now with no issues.  Im authenticating against openldap 2.3.27.  It  
appears ok.  I restarted ldap, and dovecot, and everything looked fine  
for a few minutes, then this started again.  I have around 720 users.   
Is there a setting in the dovecot.conf that I can use to fix this?  Or  
is the problem elsewhere?

What Dovecot version? The error message means that Dovecot's login_dir
(/var/run/dovecot/login) was cleaned. A few other people have been
having this problem, but I haven't yet found out any bugs in Dovecot
that would cause it. Except before v1.0.rc29 if you tried to start
Dovecot while it was already running it would do this.

I went back and looked, and you have sent a few messages to the list, 
but not once have you mentioned what version of dovecot, or provided 
dovecot -n output...

As Timo mentioned, it sounds like the auth socket is being deleted 
because it's in a place that the 'tmpwatch' tool will clean out; the
default on FC6 is anything more than 720hrs old (30 days), which fits 
right in to your 4-week observation.

Compare the location of your sockets/cache (dovecot -n) with the list of 
directories cleaned by tmpwatch (look in /etc/cron.daily/tmpwatch) and 
make sure the two aren't stepping on each other's toes.
