Problem with FreeRADIUS Active Directory Integration

6 May 2009

      In our test lab we are working on using FreeRADIUS to authenticate users against their AD credentials.  We loaded FreeRADIUS on a Fedora 10.  We loaded SAMBA and it works.  We loaded freeradius-2.1.3-1.fc10.i386.

We followed the http://wiki.freeradius.org/FreeRADIUS_Active_Directory_Integration_HOWTO.  We booted an XP workstation and logged in.  It never got a DHCP address and failed authentication.

I noticed a message,
[suffix] No '@' in User-Name = "DOM002\DW68406A", looking up realm NULL
[suffix] No such realm "NULL"
++[suffix] returns noop

In the smb.conf file we configured the workgroup to be the netbios name of the domain DOM002.  Should that have been the IP name, fm.testdomain.com?

Below is the output from the radius -X.
