After applying the latest patch cluster to a T6320 (which had not been patched in years), it was no longer able to connect to the LDAP server over SSL/TLS. I can change the authentication method from "tls:simple" to "simple" in /var/ldap/ldap_client_file" and everything works, so I know it's a SSL/TLS issue. I'm also unable to do a ldapsearch with "-Z" and "-P /var/ldap". I tested the ldapsearch command on a box that had not been patched yet and it worked.
I'm guessing that a library was updated and it's breaking LDAPS. Anybody else having this problem?
