[KLUG Members] RADIUS servers for Mobile IP

[Adam Bultman]

Good morning.  I have a  question for those (if any) of you who have 
Mobile IP type services.   I've been tasked with finding a suitable 
RADIUS server with support for Mobile IP.

We currently use freeRADIUS for our customers, and use it to 
authenticate DSL and dialup users.   However, I've been told (I haven't 
found much on the freeRADIUS site) that it doesn't support Mobile IP - 
yet.  I've been reading RFCs and other information about RADIUS and 
Mobile IP, and I don't quite understand how freeRADIUS *couldn't* 
support Mobile IP.  From what I understand, the only difference between 
normal RADIUS authentication, and Mobile IP RADIUS authentication is the 
requirement for more attributes, and for us, that's just a limitation of 
openLDAP (We use an LDAP back end, so the addition of more attributes 
requires the addition of those attributes in LDAP - not a big deal.)  
Maybe I'm wrong; perhaps reading RFCs and web pages for a few hours 
straight isn't the best for absorption. 

At any rate, we're looking at radiator 
(http://www.open.com.au/radiator/) which someone else on this list 
regards very highly. It is pricey, but again, I do not know if it is 
even necessary at this point.   

If anybody else has any suggestions for RADIUS servers that supports 
Mobile IP, that is stable, and that can potentially run on Solaris, I'd 
like to hear some horror stories or recommendations. 


Thanks in advance,

Adam
