Attributes and LDAP

Tue, 23 May 2006 03:40:56 -0700

Hi.
I am currently using FreeRadius server 1.0.2 on Solaris 8 with LDAP authentication and MySQL accounting
for PPPoE sessions with ADSL technology.
Everything works fine, but some problems appeared lately.
User profiles are stored in some subtree of LDAP server. Each user has an attribute radiusGroupName set to test
(for example). I would like to setup some common attribute values in the group profile, which is also stored in
the LDAP server but in the other subtree, and import them to user profile during authentication.
Now it does not work. Unfortunately I do not have much space to experiment because it is working
configration and I really do not have an idea how to setup this kind of behaviour.
Parts of my config files are below:
huntgroups:
cisco        NAS-IP-Address == 192.168.0.211

clients.conf:
client 192.168.0.211 {
    secret      = cisco
    nastype     = cisco
        shortname   = c7200vxr
}
