Re: OpenLDAP / PAM: No Username

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?

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

Bye for now.

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.
