Reviewing AR System server external authentication settings and configuring group mapping
Before you can properly configure BMC Atrium Single Sign-On, you must configure group mapping for external authentication in the BMC Remedy AR System server.
Before you begin
Make sure that the AREA LDAP plug-in is properly configured.
To configure external authentication for AR System
- Use a browser to log on to the AR System server (by using the mid tier).
 For example:
 http://midTier:8080/arsys
- Open the AR System Administration Console.
- Open the Server Information window by selecting System > General > Server Information.
- Click the EA tab
 (Click the following image to expand it.) 
- Verify the following information: - Field - Value - External Authentication Server RPC Program Number - 390695 - External Authentication Server Timeout (seconds) RPC - 80 - External Authentication Server Timeout (seconds) Need To Sync - 300 (default) 
- Verify that Authenticate Unregistered Users is selected.
- Verify that Authentication Chaining Mode is set to ARS-AREA.
- Set the Group Mapping.
 For example, you can map the Atrium Single Sign-On group BmcAdmins to the AR group Administrator.
- Click OK.
