openLDAP, freeRadius and firewall integration

[M. selcuk karaca]

Hi

let me pour more clearance. I accept that, I have still lots of things 
to learn and this mail list can serve this well :)


There is a firewall and this easily integrates with windows active 
directory. FW admin can easily get users and apply FW policies to these 
users. For example users can be banned from internet access.


Our aim is to implement this  with open source softwares.

we have replaced windows active directory with openLDAP server. But we 
could not integrated it with FW. openLDAP just serves for authenticating 
users. AFAIK, There is no way to integrate openLDAP with FW.


So here freeRadius comes to scene. (After this point I may be wrong, 
please advice..)


AFAIK, freeRadius can send accounting information to FW. we put 
radiusClass attribute in openLDAP user definition. and we configure 
freeRadius to get authentication information from openLDAP. if user 
logins from freeRadius then we get accounting packet including 
radiusClass attrbute travelling to our FW.

FW sees accounting packet and according to radiusClass attribute can 
decide on internet rigths


Is this a correct configuration? Are there any better ways to implement 
this?

TIA..

   That's largely how firewalls work... applying rules by users is a bit more difficult.

   FreeRADIUS doesn't generate accounting records.  It receives accounting records from a NAS or firewall.

   Because OpenLDAP doesn't generate accounting packets.

   Which does some accounting...

   I'm not even sure what you want to do.

   Your question into clear that you understand how firewalls work, how LDAP works, and how RADIUS works.
