This is strange because as I read on web this error is due to wrong
secrets configuration.
Yes. The shared secrets are wrong, or there is some miscalculation of
the reply digest.
I checked a few times and secrets are the same I
even tried to reinstall
both freeradius and libradiusclient-ng2. Please help me and point what
could be a reason for this??
Which OS are you running on? Is it 64-bit? What CPU?
The libradiusclient code MAY be doing MD5 incorrectly.
here is my radius debug (maybe will help):

That looks like a bug in libradiusclient. The Service-Type attribute
should be 4 bytes of data, not 8.
SER-Service-Type = 0x0000000300000000
SER-Uri-User = "hellboy"
NAS-Port = 0x000013c400000000
NAS-IP-Address = 0x7f00000100000000
Again, the NAS-Port & NAS-IP-Address attributes should be 4 bytes of
data, not 8.
This makes me suspect you're running on a 64-bit system, and that the
libradiusclient code isn't 64-bit clean.
Yes. I _think_ that this is the bug that chris fixed in freeradius-client 2
days ago.
Try using a current snapshot of freeradius-client instead of radiusclient-ng
and see if the problem is solved. Here is a link:

A patch I wrote to make OpenSER use freeradius-client instead of
radiusclient-ng is at:
If you run SER instead of OpenSER you may have to fiddle with the patch
slightly..
A modified version of the patch has been applied to openser cvs. (See the
comments for details)
