Description

In KerberosServiceAuthenticationProvider the method authenticate may throw GSSException. As GSSException is not a AuthenticationException this causes the ProviderManager to skip other AuthenticationProviders and lead to a 500 response in a web appliction.

GSSException is checked but not declared. See KerberosValidateAction run method. The acceptSecContext generates sometimes a GSSException.

Research direction

Start with KerberosServiceAuthenticationProvider.authenticate and KerberosValidateAction.run, then trace the acceptSecContext exception path. Confirm the failure is handled as an AuthenticationException so ProviderManager can continue to other providers instead of producing a 500 response.
