Identity does not match User-Name, setting from EAP Identity

[ZHANG Gina]

Hi all,

I have a username and identity in EAP attribute with pattern
{m=1}xxxx at xxxx.
I need to remove {m=1} for both username and identity in EAP attribute.
I put some regular expression in default file authorize section to
remove {m=1} for username and it works!
But I have not found a way to remove {m=1} for identity in EAP packet.

Any one can help?

Thanks,
Gina
