How to convert username to lowecase in NPS

I have a problem that in Cisco Prime Infrastructure I must set up all lobby ambassadors as local users matching the account name in AD. And then I can set default settings, otherwise all lobby ambassadors can set their own lifetime of tickets and so on.<o:p></o:p>

But the problem is that Cisco Prime are case sensitive in usernames. So if the user logs in with ex "Test" and the local user in Prime are "test" then Cisco prime doesn’t see this as the same user and therefore it doesn’t apply the default settings.<o:p></o:p>

So can NPS convert the given username to all lowercase?

And I'm using NPS in Windows 2008 R2.
