Symptoms

If the authentication type is HTTP headers and the log level is set to debug, an incorrect parameter gets printed, and if it happens to be NULL the websso daemon crashes.

Impact

websso daemon might crash.

Conditions

-- Authentication type is HTTP headers. -- Log level is debug for WebSSO (the single-sign-on (SSO) functionality for Web access through the BIG-IP APM system).

Workaround

Set log level to Informational. Note: The data logged specifically for debug level is targeted toward developers, and is rarely useful in a production environment.
