[Samba] samba-tool auth in scripts

[Jakob Lenfers]

Hi,

I created a script to add DNS entries with samba-tool (for LetsEncrypt,
as a dehydrated hook.) Works fine, but I have the password for the
dedicated user to do that in the script in the clear. I think I read
somewhere something about doing it with kerberos, but I never used
kerberos and don't know where to start. Is there any good way to be
doing this?

Thanks,
Jakob
