[Serusers] FreeRadius MD5 Problem

I'm facing some really weird problem. Let's try to explain, but first my config (basically): OpenSUSE 10.0 FreeRadius 1.0.4-4 RadiusClient-NG 0.5.2 SER 0.9.6 MySQL 5.0.18 THE GOALs: upgrade from SER 0.8.4 to 0.9.6; MySQL from 4.0 to 5.0. THE SCENE: FreeRadius, using MySQL as back-end, as SER. SER configured to consult Radius and make account on both places (Radius and MySQL). I have this same configuration running and OK, but on an old version of SER (0.8.4) + MySQL 4.0 + RadiusClient-NG 0.5.0. MySQL is running OK and responding to all queries, as expected. THE PROBLEM: with the upgrade the RadiusClient-NG is reporting that the digest (MD5) returned by the Radius server isn't correct. If I tweak the code of sendserver.c (radiusclient-ng-0.5.2/lib/sendserver.c) to compile it with DEBUG displays, it shows me that different digests. One that comes from FreeRadius and another calculated. So now I stuck... I can not go on with the upgrade 'til I find a solution to this issue. Not using Radius is not a possibility. Did anybody cross this problem and find a solution? Edson.
