# Active Directory

When using Active Directory as the security mode, the user name and password will be checked against the domain.

1. In the User Configuration dialog, set the Authentication Mode to Active Directory.

2. Press the Configure button to setup the Domain name that is going to be used.

3. The custom user fields will now attempt to read their data from the user's profile on the Active Directory server. The Name field is actually a property of the user's profile, so it will be automatically populated. The IsMemberOf keyword will iterate through the Active Directory's list of groups and check if the user is a member.

   For information on using a custom user field to assign access levels, see the topic Locating a User's Group Memberships.
