Is a backport to UCS 3.3 required?

+++ This bug was initially created as a clone of Bug #41406 +++

The patch of Bug #36101 needs to be backported to UCS 3.2 as well, due to the errata3.2-8 update to Samba 4.3.7. For UCS 3.3 this has already been done
(see Bug #40698 Comment 8).


+++ This bug was initially created as a clone of Bug #36101 +++

Samba 4.2 creates additional SRV records in DNS, which are not accepted by the UDM syntax class ipProtocolSRV. This causes rejects in the S4-Connector:

UCS rejected

Can't find the MS docs where these are specified but apparently that's what Active Directroy creates. Note the "DomainDnsZones" and "ForestDnsZones" parts in the DNS names (these are not to be confused with the equally named LDAP partitions in the Samba4/AD Directory Service).
