Administrator account not working and Kinit unable to reach any KDC in realm

Hello - I am having an issue getting my Administrator Account authenticated to login to the web interface in Univention 5. It seems to be related to Samba 4, and I am working through a fix here: Problem: Kinit unable to reach any KDC in realm

On this command, I am able to see the host ip address, but it has a port added (88). I am not sure if this might be the problem, or if it is something added by UCS in 5.0. Any help appreciated! I am unable to use the administrator account anywhere, and had some issues with samba 4 in the upgrade process.
