When you add a user in RMM Central and make them authenticated via Active Directory, you get an error as "The user can be authenticated only through the machines: XXX"


To be able to authenticate a user via Windows Active Directory, the user should have access to logon to the Domain from the computer where RMM Central Server is installed.

Windows Active Directory provides the flexibility for the administrators in restricting the users logon computers and logon times. If a user has been restricted to logon to the domain only from specific computers, you will get this error.


You should make this user login to the Domain from the computer where RMM Central is installed. Follow the steps below on the computer where the Domain Controller is installed:

  1. Select Start --> Programs --> Administrative Tools --> Active Directory Users and Computers. This will show the lists of users available in the active directory.
  2. Right-click the user that you are trying to add in RMM Central and click Properties.
  3. Select the Account tab and click Log On To button
  4. This will list the computers from where the user has access to login to the Domain. Specify the name of the computer where RMM Central Server is installed and click Add.
  5. Click OK to close the Logon Workstations dialog.
  6. Click OK to close the user properties dialog.
  7. Close the Active Directory Users and Computers window.
