Does the iRule command "PROFILE_auth" still work in v11?

Hi,

I was looking at using this iRule command to grab the name of the Auth profile being used: [PROFILE::auth name] but i get a wrong arguments error no matter which setting I try. We're using 11.4.1.

DevCentral iRule command reference

I know that in general LTM Auth (ACA) is an old feature on its way out, however it is still supported in current releases so I'd expect the command to be supported also.

Any hints?

Thanks, Andrew
