Hi, When radiator does it's simultaneous use double check, it checks the username on the router against the one in question... however as we feed the users through a regex, these will be different (e.g. users logging in with a capitalised username, etc). e.g. user logs in as [EMAIL PROTECTED] (which will be what the Cisco shows up on a who). However radiator will think of them as simply "twit" - hence they can log in as many times as they like provided they dont log in with simply "twit" I'm not sure if this can be classified as a bug, but if it were treated the same as the username being authenticated it would stop this happening. Anyone have similar problems? Justin === To unsubscribe, email '[EMAIL PROTECTED]' with 'unsubscribe radiator' in the body of the message.
