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

I get a few of these errors in our syslogs every hour, and occasionally it seems I can't log in via SSH. However typically when I log in to the machine and do a "getent passwd" everything is fine. The LDAP server is from Open Directory in OS X Server 10.5.2. The version of nss_ldap is the one from Gentoo Linux, version nss_ldap-258.

My /etc/ldap.conf looks like this:

uri ldap://ldap1.example:389 base dc=example,dc=com timelimit 30 bind_timelimit 30 bind_policy soft nss_reconnect_maxconntries 5 idle_timelimit 3600 pam_password_prohibit_message Please use System Preferences on your Mac to change your directory password. nss_base_group cn=Groups,dc=zymeworks,dc=com nss_base_passwd cn=Users,dc=zymeworks,dc=com

Does anyone have any suggestions as to what I can try to do to debug and fix this ? It's really becoming irritating.
