openldap authentication problem
Hello,
Since a few days, I am having authentication
problems with my openldap server.
The system:
SuSE Linux 8.2
openldap 2.1.12
pam_ldap version 159
nss_ldap version 203.7
I am using all default versions coming with the
distributions. Everything broke a few days ago
and I am currently not able to login any more,
but am always seeing an "(Insufficient access)"
message in the logs.
I append my slapd.conf file, the ldap.conf
file and the output of the full log (obtained
with loglevel set to -1) from /var/log/messages
of a failed login attempt.
BTW, the system broke after restarting
the ldap server. I was editing slapd.conf
but as far as I am aware of, I left
everything as it was before (when the
system was running). It is very possible
that I did change something but after
looking for it for a few days I just
can't see what it could be.
Any idea as to what may be wrong?
Thanks!
Vuko
