Document Passing role to NoAuth / ExternalAuth via apache2 auth plugin

[shujaaa]

I can find some doc on how to set the REMOTE_USER but not on how to pass more info, including role, and some fields to be automatically put in the generated certificates (exemple, email and OU).

I can set any apache env variable to my desired role for example, but I cannot find a way to pass that to the authentication layer. In the tests there is a "NoAuth with role" test, so I'm assuming this is indeed possible.

Maybe consider adding that to the documentation ?

Thanks,
