I'm using nss_ldap on a whole bunch of machines on the network,
and
while it works great most of the time, I continuously get errors in my
syslog. A sampling from today (these are actually from different
machines, but I have anonymized the hostnames to be the same.):
Feb 25 09:30:25
server.example.com sshd[17495]: nss_ldap: could not
search LDAP server - Server is unavailable
Feb 25 11:11:08
server.example.com -bash: nss_ldap: could not search
LDAP server - Server is unavailable
Feb 25 21:50:01
server.example.com automount[5030]: nss_ldap: could
not search LDAP server - Server is unavailable
Feb 25 21:55:16
server.example.com nscd: nss_ldap: could not search
LDAP server - Server is unavailable
This happens with processes that do fork(). Samba is a great example.
Newer versions of nss_ldap have this fixed (I can't precise which
version right now).
