Works fine, I was able to create a network of few IPA 2.2 replicas and IPA 3.1
replicas and use ipa-replica-manage and ipa-csreplica-manage to play with the
agreements. No regression discovered so far.
I just see that in patch 101 you touch setup_replication and force TLS as a
default. But in this case, r_sslport parameter is never used and we can remove
it.
In 101, you also set LDAP+TLS as default connection protocol with
+ super(CSReplicationManager, self).__init__(
+ realm, hostname, dirman_passwd, port, starttls=True)
^^^^^^^^^^^^^
Wouldn't we want to make LDAP+TLS as a default also in a bunch of
ReplicationManager initializations in ipa-replica-manage? Otherwise, we use
ldaps/SSL by default. AFAIU, LDAP+TLS is preferred over ldaps/SSL so this would
be a good step to do. Adding Rob and Simo to CC to correct me if I miss
anything and we want to keep using ldaps/SSL by default.
