I don't have an answer for your problem, but I've had something similar:
OS: Mandrake 9.1
~From the local machine everything worked well nss_ldap, pam_ldap, samba,
phpLdapAdmin, lam, gq, etc. Connecting over TLS, SSL or without
encryption. However connecting from remote clients, even anonymously,
with, or without encrypted connections, sometimes freezed (the processes
were running, but the connecting clients had to wait forever for an
answer, so with nss_ldap, and pam_ldap it made the system hanging)
openldap. Unfortunately I wasn't able to find out the origin of the
problem. But it seems that upgrading to openldap-2.1.22 solved it.
