The User Account Override policy allows administrators to add users to the override list and selectively set account attributes for those users. This policy manages the Safeguard Authentication Services user-override file, which allows specified users to take on a different identity on a per-machine basis.
To add a user override entry
-
Start Group Policy Editor.
-
Navigate to the UNIX Settings > Safeguard Authentication Services > Identity Mapping node.
-
Double-click User Account Override to open the User Account Override Properties dialog.
-
Click Add.
TheUser Account Override dialog opens initially with all fields disabled except the Apply To field.
-
Enter the specific DOMAIN\sAMAccountName or a * in the Apply To field.

The entry displays in the list of account override settings. Scroll the list or adjust column widths to view all of the account settings.
-
Click OK to save settings and close the dialog.
By using Group Account Override, you can add local users to Active Directory groups. The Group Account Override policy allows administrators to append a group membership list to the list stored in Active Directory. You can also override the group name and GID (group ID) fields.

The Host Access Control policies give you fine-grained control over which users are allowed to log into the UNIX host.
Safeguard Authentication Services supports host access control through the users.allow and users.deny files. Safeguard Authentication Services consults these files to determine whether or not to allow access to a particular user. This is an effective way to restrict access to sensitive computers on the network when using decentralized user accounts such as Active Directory. Group Policy defines policies for management of the access control files.
Host access control entries are "append only" and cannot be overridden. However, if there is a duplicate entry, the entry is only added once to the access control files.
The Configure a User Allow Entry policy manages the Safeguard Authentication Services users.allow file. This file controls which users are allowed to log in to the host machine. If any allow rules are set, then a user must be allowed access through one of the configured allow rules or the user is denied.
To set up an allow entry
-
Navigate to the UNIX Settings > Safeguard Authentication Services > Access Control > node.
-
Double-click users.allow Configuration in the result pane to open the users.allow Configuration Properties dialog:
-
Click Browse AD to add a container. All users under the specified container are allowed to log in unless a deny rule prevents it. All other users are denied login access unless another allow rule allows it.
-
Click Add Group to add a group. All group members are allowed to log in unless a deny rule prevents it. All other users are denied log in unless another allow rule allows it.
-
Click Add User to add a specific user. The specified user is allowed to log in unless a deny rule prevents it. All other users are denied log in unless another allow rule allows it.
-
Click Add Domain to add a domain. All users in the domain are allowed to log in unless a deny rule prevents it. All other users are denied log in unless another allow rule allows it.
-
Click Add Custom to add an item manually. You must specify the correct type for the item. All users associated with the specified item are allowed to log in unless a deny rule prevents it. All other users are denied log in unless another allow rule allows it.
-
Click OK to save settings and close the dialog.
