Realm question

[Jeff Crowe]

Hi all,

Sorry if this question has been answered (I did search the archives and
google to no avail):  I have subscribers that connect with 2 realms as the
prefix.  How do I strip both and just authenticate locally?

IE: username: realm1/realm2/username  or realm1/realm3/username.  Realm1
will always be present followed by either realm2 or realm3 (no others).

Thanks,

Jeff
