MSCHAPV2 authenticate including the suffix

Hello, I am using an SQL backend. The usernames are stored with the full username including a suffix 'user@domain.com I am trying to use TTLS/PEAP with MSCHAPV2 So I want freeradius to authenticate the full username, not the stripped username. I want it to match 'user@domain.com<mailto:user@domain.com>' not 'user' When trying to authenticate, it says: [mschap] ERROR: User-Name (user@domain.com<mailto:user@domain.com>) is not the same as MS-CHAP Name (user) from EAP-MSCHAPv2. If I set the username in the database to just 'user' and send that through in the supplicant, it works. But I want it to work with the full username including the suffix in the database. Is this possible? Thanks for your help Dean.
