It's a bit awkward, but you can import and call the samba-tool commands 
directly within Python (samba-tool of course is written in Python). See 
an example of this hack here:
https://github.com/yast/yast2-dns-manager/blob/master/src/modules/SambaToolDnsAPI.py 


This example uses username/password for auth, but the CredentialsOptions 
parser can be instructed to use the keytab, IIUC: 
https://gitlab.com/samba-team/samba/-/blob/master/python/samba/getopt.py?ref_type=heads#L384 


If you don't like this hacky approach, you could re-implement something 
using the same calls made by samba-tool: 
https://gitlab.com/samba-team/samba/-/blob/master/python/samba/netcmd/dns.py?ref_type=heads

This is probably a more appropriate approach, but a bit more work.
