Fix deadlock in init_ldap_connection()

From: Leonardo Chiquitto <leonardo.lists@gmail.com>

Commit 9fc20db13 ("fix crash due to thread unsafe use of libldap")
introduced a deadlock in init_ldap_connection(). When TLS is on,
this function will call itself recursively and try to lock a mutex
that's already owned by the thread. Fix the problem by using the
lockless version.
