Active Domain Controller server lists (part of SSSD-AD)?

[Conwell, Nik]

Hi all, just curious what do you all do for Active Directory domain controllers in the
krb5.conf?  Seems like "realm join" by default populates the krb5.conf with the
hostnames of all the AD KDCs discovered for the domain.  All good until we decided we are
going to rename the KDCs to all new names.  Windows boxes don't care, apparently they
will automatically rediscover based on the "_srv_" record queries.  But from an
SSSD-AD and krb5.conf perspective we may end up having to "realm leave"
"realm join" the linux boxes to pick up the new DCs or possibly edit the
krb5.conf to change the discovered servers to be just "_srv_" so it will be
dynamically queried.

What are you all doing for SSSD-AD and the list of AD Domain Controllers?  Do you manage
the krb5.conf list directly, or do you just always change the list to be
"_srv_"?

Thanks.
