It is for my usecase. From what i see, this problem cannot be easily
solved for the Ubuntu provided Samba package, as that depends on libldap
which pulls in Heimdal kerberos and also on libcups which depends on MIT
As a first step, it should be possible to have a simple Samba file
server build that works with a system provided Heimdal kerberos.
