AuthDomain.accepts

Checks if msg contains appropriate authorization for domain to accept it.

Mirroring [soup.auth_domain.AuthDomain.covers], this does not check whether or not domain cares if msg is authorized.

This is used by classServer internally and is probably of no use to anyone else.

Parameters

msga #SoupServerMessage

Returns

the username that msg has authenticated

as, if in fact it has authenticated. null otherwise.
