Hello All, Let me just say I'm a big fan of FreeRADIUS and highly appreciate the work and effort put in to this project. We've been thinking of ditching our current cisco Radius server as it has been prone to massive memory leaks, daily restart required. We did some testing of FreeRADIUS with one of our NAS gear, Samsung's General ATM Switch Network (GAN) deployed in a 3GPP2 EV-DO network. Things didn't go as I'd hoped. Following is the output of Radiusd -x.

Going to the next request Waking up in 4.9 seconds. Cleaning up request 2 ID 254 with timestamp +62 Ready to process requests. As you can see access-accepts are being sent to the NAS with the callback-id but the user is unable to connect. From what I am able to understand the NAS is sending a 3GPP2-Attr-60 VSA which is the 3GPP2-HRPD-Access-Attribute not defined in the 3GPP2 dictionary of Freeradius but is defined in Cisco' Access Registrar would patching the 3GPP2 dictionary do the trick or am I missing something? I would've tested this already but this would require approval from other departments as well which in gonna take a couple of days but any help in this matter would be appreciated. Regards.
