Hi Matthew
How does changing the auth method alter who can get on?
If I use NTLM_AUTH/WINBIND - it's harder to restrict access to a particular AD Group ("valid user, valid credentials = accept" versus LDAP: "valid user, valid credentials, correct group entry = accept") - no? Since I've read here over the past week or so everyone simply says "use LDAP" when the question of AD group restriction is posed - I got the impression that moving to LDAP would be the way to go...
