Unitialized value and no value sent for attribute at Radius.pm

Dear all,

I am new in Nocat, Freeradius, and even in linux.

I have installed NoCatAuth-0.82 gateway and authserv in two different
rh9 boxes.  Freeradius-1.0.1 was installed in the same boxes as the
authserv. I have installed pogozone
NoCatAuth-0.82+RADIUS-20031015.patch in both the gateway and authserv,
and loaded nocat dictionary to the freeradius dictionary.

I could login to nocat, the radius accounting works, and simultaneous
use could be limited to only 1 for any user.

However, after login I could not directly redirected to the url
requested within 5 seconds.  I can go to the url after clicking the
link in the page that appeared after the login page.

There are two errors in my nocat.log that I couldn't manage to solved :

[2005-02-21 00:38:45] no value sent for attribute 4 at
/usr/local/nocat/bin/../lib/Authen/Radius.pm line 347.
[2005-02-21 00:43:45] Use of uninitialized value in subroutine entry
at /usr/local/nocat/bin/../lib/Authen/Radius.pm line 339.

I have learned nocat list archived, but can't find solution.  I am
sorry if the topic have been discussed.

Could someone help me to solved the problem?  Any help would be appreciated.

Regards

Ery
