[nssldap] nss_ldap: could not search LDAP server

[Richard Lefebvre <Richard.Lefebvre [at] rqchp.qc.ca>]

I upgraded 6 systems from SuSE 9 to SuSE 10 (i.e. reinstalled from 
scratch). I use LDAP for a user database and all seems to working OK. I 
only get problems with PBS queueing system, within a job, I can't seems 
to be able to see all the groups that the user belongs to, yet by just 
login to the system, it's OK. In the /var/log/messages I get the following:

pbs_mom: nss_ldap: could not search LDAP server - Server is unavailable

I'm a bit confused that to what exactly is happening. Below is the 
ldap.conf of the LDAP client (openldap2-client-2.3.19-18.11).

host    10.0.0.1
base    dc=all,dc=local
ldap_version    3
bind_policy     soft
pam_check_host_attr yes
pam_password    crypt
ssl     start_tls
nss_map_attribute       uniqueMember member
pam_filter      objectclass=posixAccount
nss_base_passwd dc=all,dc=local
nss_base_shadow dc=all,dc=local
nss_base_group  dc=all,dc=local

P.S. Does the "ssl start_tls" assures that all the communications 
between client and server are encrypted? The server is RH4, 
openldap-2.2.13-4.
