[Serusers] Hi All. a newbie question about SER + auth_radius: loadmodule fails

[itsik]

I'm trying to enable radius auth, but the loadmodule fails. I installed the
libradiusclient 0.3.2 and I c libradiusclient.so in /usr/local/lib.

I saw the advice about adding /usr/local/lib to the /etc/ld.so.conf and
running ldconfig -v. I even saw that it handles the libradiusclient.so.
Then I tried to fool auth_radius by adding a link to libradiusclient.so
named libradiusclient.so.2, but then it didn't find some symbol rc_dict..

The configuration file is the default file, except the loadlodule for
auth_radius and replacing www_auth with radius_auth.
The ser output is:

.

a.	why does the auth_radius looking for 'libradiusclient.so.2' doesn't
it seeks the 'libradiusclient.so'? 
b.	what can I do in order to make it work?

Thx in advance,
