Hi, I have running a Samba 3.0 PDC authenticating off ldap via pam and it is running well. We have two branches in ldap ou=internal and ou=external. I would like to disable machine logins for the ou=external group of users but still keep network logins working. This is so that we can still use those username/password combinations for IIS authentication but block them from being used to log into local machines. Things we have tried: Adding an extra filter to the pam_ldap config for samba to filter out the external people on "account" and "session", unfortunately it won't let you disable just one or the other Disabling the account with the "D" flag in sambaAcctFlags. This just outright disables the account for all logins which is what I suspected Tried to use user manager for domains but that didn't get me anywhere, it simply wouldn't let me set the log on locally policy. I have also tried to find the registry key to change to set which groups are allowed to log on locally and put it into NTConfig.pol file on netlogon share but haven't found what I need to set or even whether this will work. Any help would be greatly appreciated Matt __________________________________________________ This Message is intended for the addressee named and may contain confidential information.
