restricting access for users

[Martial VdB]

Hi Alan,

thank you for replying,

this is how I tried this before, I will try to keep this as short as 
possible.

1)
users:
bob       Password == "bob", Huntgroup-name == "diegem"
          Login-Service = 0,
          Vendor-Specific = 9,
          Reply-Message = "Hello, bob",
          Cisco-AVpair = "shell:priv-lvl=15",
          Service-Type = NAS-Prompt-User,

huntgroups:

diegem             NAS-IP-Address == 10.5.x.x
diegem             NAS-IP-Address == 10.5.x.x
diegem             NAS-IP-Address == 10.5.x.x
brussels            NAS-IP-Address == 10.2.x.x

I hoped that the nas ip addresses belonging to diegem where only accessable 
for users who had Huntgroup-name == "diegem" in their config.  But this did 
not seem to make a difference.

2)
users:
DEFAULT   Auth-Type = System
          Login-Service = 0,
          Vendor-Specific = 9,
          Service-Type = NAS-Prompt-User,
          Cisco-AVpair = "shell:priv-lvl=15",
$enab15$
bob
bobke

huntgroups:

diegem             NAS-IP-Address == 10.5.x.x
diegem             NAS-IP-Address == 10.5.x.x
diegem             NAS-IP-Address == 10.5.x.x
                       Group == NOC,
brussels            NAS-IP-Address == 10.2.x.x

I made bob and bobke local users on my machine and added them to # groups. 
bob to NOC and bobke to brussels.
bob:x:1005:1005::/home/bob:
bobke:x:1006:1006::/home/bobke:
NOC:x:1005:
brussels:x:1006:

If the user was not a member of group NOC he would be refused on the NAS 
servers belonging to huntgroup diegem.Because diegem is linked to group NOC 
(Group == NOC). This did not work either.

In both cases every user was allowed access as soon as the username and 
passwords checked out. I also had problems with nas ip addresses belonging 
to more that 1 group. It looked like the groups are processed from top to 
bottom and as soon as it hits the first entry of that address freeradius 
allowes access.
But for my problem to be solved it should cache information like Group = NOC 
or for example user_pool = diegem. And compare this information agains an 
entry in
the users file like: user_pool=diegem or checking if on the system bob's 
primary group is NOC.

I did several more combinations but I think one of these 2 should work. 
Perhaps I made a configuration error ?

Big thank you in advance ony for reading and getting into this problem. If I 
was not clear enough please let me know.
