[RADIATOR] UserName Rewrite Function

[Rianto Wahyudi]

Hi, 


We have MySQL database containing email alias which map into Active Directory user. 
Ie : rianto.wahyudi at latrobe.edu.au mapped to rwahyudi at ltu.edu.au


I would like to utilize this database so user can login with their email address or their AD username. 
Is it possible to pass UserNameRewrite to a function or another perl script ? 

All authentication are done via NTLM, and I believe radiator use ntlm_auth program.
Is it possible to create a wrapper for ntlm_auth script ? 

Here is my handler setup : 

# STUDENTS DOMAIN TTLS
<Handler Client-Identifier=Eduroam-Server, TunnelledByTTLS=1,Realm=/students.*/i>
    RewriteUsername s/^\@.*//
    <AuthBy NTLM>
        EAPType MSCHAP-V2
        Domain STUDENTS
        UsernameMatchesWithoutRealm
    </AuthBy>
</Handler>
