Specifying authentication chaining mode
You can specify the order in which internal and external authentication methods are attempted by specifying a value for the Authentication Chaining Mode field.
When Authentication Chaining is enabled, all authentication methods in the chain are attempted in the specified order until either authentication succeeds or all the methods in the chain fail.
To set the authentication chaining mode
- Open the AR System Administration: Server Information form, and click the EA tab.
- In the External Authentication Server RPC Program Number field, enter 390695.
- Select Authenticate Unregistered Users, Cross Reference Blank Password, or both.
- From the Authentication Chaining Mode list, select one of these values:
