 Title: #392: GPO: Don't use freed LDAPURLDesc if domain for AD DC cannot be found
Action: opened

PR body:
"""
If a referral returned during AD GPO processing cannot be assigned to a
known domain, at the moment SSSD accesses memory that was freed previously
with ldap_free_urldesc().

This patch moves the ldap_free_urldesc() call to both the error handler and
the success branch after we are done working with the LDAPURLDesc instance.
