SAMBA in this setup will not act as a logon server. The configuration described in this section will setup SAMBA as a CIFS server, and only that. It is assumed that users and clients logon against Kerberos and LDAP as described in previous documents.
After users have received their Kerberos ticket, they can start using the SAMBA services. Meaning that SAMBA has to honour connections with a valid ticket. And deny all other access.
