# Active Directory Authentication

In Active Directory mode, the user name and password are maintained by your IT department.

You may access a subset of user properties from Active Directory that includes "EmailAddress" and "VoiceTelephoneNumber". For the full list of properties, see the User Fields And Data topic.

If you wish to use Security access level AD users, you will need to add your AD user names (not passwords) to the local Database: runtime.db3. For the full list of properties, see the User Fields And Data topic.
