Problem with shared secret on H3C WX5004

Hello everyone, Yes, I've known that H3C WX5004 is too old wireless controller, but it is that I have in moment. :D I've already radius configuration in WX5004 that pointing to a freeradius server 2.x. Aiming to test freeradius 3.0.15, I've configured another radius configuration and pointing to freeradius server 3.x, but when Access-Request arrives to freeradius 3.x, freeradius drops because shered secret is incorrect. Thus, I have two questions: 1. Is there a method to check shared secret in message sent to freeradius? 2. Someone have similar problem with this controller (H3C WX5004) Att., -- Igor Sousa
