Hi,
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).
Any ideas?
You're probably running nscd. Google it. Then get rid of it.
