PPTP/PPP/Radius/LDAP and usernames in email format

Sorry all, it would seem that a bit of HTML got caught up in the

Hey all,

Heres's one for you. I am currently setting up a new MS-ChapV2/MPPE VPN 
gateway with pptp/ppp to freeradius authing against an LDAP store.

This VPN will be used for multiple client domains and so I would like to 
use usernames in the form of „user@domain.tld“ instead of „user“ (which 
is the situation atm).

The LDAP store has a branch as follows:

ou=domains,dc=company,dc=com

under ou=domains I have entries for each domain that I will be offering 
VPN access to.

ie. cn=domain.tld,ou=domains,dc=company,dc=com

I would like to get ppp to send the complete user@domain.tld to radius 
and have radius use the „domain.tld“ as part of the filter for the 
username search to limit the search to the sub-branch from the correct 
domain.

The problem is that I have yet to find a way to get ppp to send the 
username to Freeradius if there is an @ symbol in the username.

Any ideas?

thanks,
chuck
