About Kerberos Auth
A Kerberos Auth action retrieves user credentials using a Kerberos ticket.
Note: In an access policy, an HTTP 401 Response action typically precedes a Kerberos Auth action.
A Kerberos Auth action provides these configuration elements and options:
- AAA Server
- Specifies a Kerberos server; servers are defined in the Access > Authentication area of the Configuration utility.
- Request Based Auth
- Specifies whether per request based authentication is enabled. When disabled, authentication occurs only while executing the access policy.
- Max Logon Attempts Allowed
- Specifies the number of user authentication logon attempts to allow. A complete logon and password challenge and response is considered as one attempt.
Note: For a per-request policy subroutine, equivalent functionality is supported through subroutine settings.
