This topic describes how to configure an NT Domain authentication server on Forefront Unified Access Gateway (UAG).
When using NT Domain authentication, open these destination ports to your corporate domain controllers:
- RPC services: 1025-5000 (TCP)
- RPC portmapper listener: 135 (TCP)
- RPC in NT 4.0: 139 (TCP)
Make sure that the server is configured to enable users to change their password while authenticating against the NT Domain authentication server, if required.
To configure an NT Domain authentication server
-
In the Forefront UAG Management console, on the Admin menu, click Authentication and Authorization Servers.
-
On the Authentication and Authorization Servers dialog box, click Add.
-
In the Server type list, click NT Domain.
-
On the Add Authentication Server dialog box, configure the following server settings:
Note: On the Add Authentication Server dialog box, you can also define the local computer Windows Local Users and Groups manager as an authentication server, or for portal trunks, define the authorization user/group repository. - Server name—Name of the server or
repository. This name is used when you select the server or
repository during the configuration of Forefront UAG. It is also
displayed to end users when they are prompted to select a server
during authentication.
- NT Domain—Name of the NT domain, or if
you are defining the local computer, the name of the local
computer. The name you enter here is used by default as the user’s
login domain name.
- Level of nested groups—Defines whether
to search for the user in additional groups to which the user
belongs, and the number of nested groups in which to search:
- Using the default value, which is 0, the
search includes only the groups to which the user belongs directly.
For example, if the user John is a member of group QA, the search
includes the group QA, but not any of the groups to which QA
belongs.
- If you enter a value other than 0 in this
field, it defines the number of nested groups included in the
search. In the above example, if you enter 1, and QA is a member of
the R&D group, the search includes both the QA group and the
R&D group.
- If you leave this field empty, the number of
nested groups is unlimited. The search includes all the groups to
which the user belongs, both directly and indirectly.
- Using the default value, which is 0, the
search includes only the groups to which the user belongs directly.
For example, if the user John is a member of group QA, the search
includes the group QA, but not any of the groups to which QA
belongs.
- Server access credentials—The
credentials you enter here are used to access the NT Domain server,
and perform Server access functions such as retrieving the
users/groups lists, retrieving user information, and changing
passwords. If you enter access credentials, make sure you fill in
all the Server access credentials fields.
Note: If you are defining the local computer, select the Anonymous logon check box to disable the Server access credentials fields and enable anonymous access to the Windows Local Users and Groups Manager. - User—User name that is used to access
the NT Domain server. The user you assign must have Read
permissions (or higher) on this server.
- Password—Type the password of the user
you defined in User.
- Confirm password—Type the password
again for confirmation.
- Domain—Type the domain of the user you
defined in User.
- Anonymous logon—Select this check box
to disable the Server access credentials fields and allow anonymous
users to access the server (or if you are defining the local
computer, to the Windows Local Users and Groups console), and
perform the Server access functions.
- User—User name that is used to access
the NT Domain server. The user you assign must have Read
permissions (or higher) on this server.
- Server name—Name of the server or
repository. This name is used when you select the server or
repository during the configuration of Forefront UAG. It is also
displayed to end users when they are prompted to select a server
during authentication.

On the Add Authentication Server dialog box, click OK, and then on the Authentication and Authorization Servers dialog box, click Close.
