I have several OSX Ventura 13.3.1 machines that I need to connect to a Samba Active Directory. After entering the Samba credentials in the Mac Directory Utility, I get the following error:

Authentication server could not be contacted.

Other machines can successfully connect, including windows 7,8,10,11, as well as older versions of macOS

I can successfully run the following DNS verification from the Mac terminal:

host -t SRV _ldap._tcp.samdom.example.com.
host -t SRV _kerberos._udp.samdom.example.com.
host -t A dc1.samdom.example.com.

Server information:
OS Ubuntu 22.04.2 LTS
Samba Version 4.15.13-Ubuntu
