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.
Hi Howard,
thanks for your reply. I've disabled ncsd for now. Do you have any idea how I could force the error to test if ncsd really was the reason?
Bye for now.

Leave nscd running. The next time you see the error occur, stop nscd.
Bye for now.

Well, last time it took about a week until the error showed up. So it would be nice to force it. But I'll wait then. Still have some Samba/Win7-Problems so it will take some time anyway to go into production mode.
Thanks again for your help.
