get only username from REMOTE_USER variable

[mnikhil@gmail.com]

Hi

Firstly, My Sincere thanks to all of you for making available such a
wonderful module available to Apache on sourceforge.

My problem is nothing except that to make modifications to REMOTE_USER
variable in the kerberos itself.
I mean when I am visiting a kerberos enabled webpage, after succesful
authentication the REMOTE_USER variable is being set as
"<user>@<mydomainname>"
I guess here the <domainname>, obviously it takes from domain_realm,
set in the /etc/krb5.conf page.
So, I want to make changes something that could make REMOTE_USER
variable just the "user" and not the "<user>@<mydomainname>".

Response would be much appreciated.

Regards,
Nikhil
