RE: Proxy Question

24 Apr 2006

      It gets to the pre-proxy, adds the domain after the user name, but doesn't
strip out the 'DOMAIN\\\\'

Do you see any evidence that the 'ntdomain' is actually doing anything? I
don't see much of anything except the one line 'modcall[authorize]: module
"ntdomain" returns updated for request 0'

Any other ideas Phil / Group?

Thanks,
-Reynold

Thanks for the reply.
I forgot to mention that I had 'ntdomain' addedd to the authorize stanze.
The request is getting to my IAS server, but IAS doesnt understand 
"DOMAIN\username" it does, at least in my implementation, understand 
"username@domain"...
Gah. Shudder.
...
Is there a way to get "DOMAIN\username" converted to "username@domain"?
You could try this in /etc/raddb/preproxy_users

DEFAULT
         User-Name := `%{Stripped-User-Name:-%{User-Name}}@%{Realm}`

Be sure to add the "files" module to the "pre-proxy" section in radiusd.conf
like so:

pre-proxy {
   files
}

Seems to work here for me, with the exception that requests matching the
DEFAULT realm e.g. "foo\username" are sent as "username@DEFAULT" instead of
"username@foo". Annoying, but not an issue if you're explicitly spelling out
your realms.

If you need both styles:
modules {
        ..
        realm suffix {
                format = suffix
                delimiter = "@"

                ignore_null = yes
        }
        realm ntdomain {
                format = prefix
                delimiter = "\\"
                ignore_default = no
                ignore_null = yes
        }       
        ..
}
authorize {
        ..
        suffix
        ntdomain
        ..
}
Please run radiusd -X if this doesn't work,
