Specifying internal and external authentication

By default, BMC Remedy AR System attempts to authenticate users internally. In all cases, if the user and password match a record in the User form, authentication succeeds. Similarly, in all cases, if the user and password do not match a record in the form, authentication fails.

To use external authentication, select one of the following options in the EA tab in the AR System Administration: Server Information form:


If the user group information is returned through external authentication, you cannot be a part of any administrator group. You can be a part of the administrator group only from the User form.

  • Cross Reference Blank Password — If a user does not provide a password, BMC Remedy AR System tries to cross-reference the user with an external source. See Cross-referencing blank passwords.


To use external authentication, you must set the External Authentication Server RPC Program Number field to 390695.
