Subject: [PATCH 156/160] GPO: Extract server hostname after connecting

https://fedorahosted.org/sssd/ticket/2543

The LDAP URI is not valid prior to connecting to LDAP. Moreover,
reconnecting to a different server might invalidate the URI.

Move reading the URI after the connection has been established.
