Yes, I think this is exactly the right approach. The only other thing
you might consider is if you can create the cn=samba-admin,cn=samba user
via an 'initial LDIF' fragment into FDS.

Yes, you should do this against ldapi directly.

There is actually a great example already in the script - see the code
that tries to see if an LDAP server is already bound to the ldapi
socket. (This code is looking for the exception, but you will be
looking for and using the resulting context).
This is on line 1358.

Line 1648 sets this for OpenLDAP:
# Set the username - done here because Fedora DS still uses the admin DN and simple bind
Line 1712 sets this to the Manager DN (not sure if that is actually
successful) for Fedora DS:
