i'm trying to do something similar to your scenario.
I was planning to have two zentyal servers. 1 master a 1 slave, sync users, etc,
I have read in Zentyal DOC (spanish) that zentyal master server can be ONLY used to LDAP and DNS service, cant be used to samba shares.
My plans are, have 2 server, users & groups sunc'ed, samba shares on both of them,
This can't be done, ehh
Somebody pls help
