Marking a user as inactive

To mark a user as inactive, open the Users module under the User Administration application, and open the record of the user you want to mark as inactive. Uncheck the Active checkbox and click on the Update button. Marking a user inactive hides them from all reference fields. Thus, no one can select the inactive user or request any task on their behalf, as shown in the following screenshot:

Furthermore, marking a user as inactive also executes a server-side script (Lock Out Inactive Users business rule), which in turn also set the locked out value to true thus causing the user's sessions to be terminated and being locked out.
