OpenLDAP / PAM: No Username
I'm running OpenLDAP 2.4.23-7.2 (from Debian Squeeze). Most of the time
everything works fine, the LDAP-Server is used by libpam/libnss, Samba,
Dovecot and Postfix. Sometimes when I log into the Server via SSH the
command prompt displays "Ich habe keinen Benutzernamen@servername"
(which means "I don't have a username") instead of my username. The
login itself works fine. The real problem is that if this happens the
Mailserver isn't able to deliver mails:
status=bounced (unknown user: "myusername")
Using google I found some other users with the "don't have a
username"-Problem, but most of the time they had a ACL-Problem. As the
LDAP-Server usually is working it seems that this isn't the problem.
Also the problem is gone when I restart the whole machine (just
restarting slapd doesn't help).
