New to FreeRadius, having a small issue

Hey Everyone, I am new to freeradius, and when receiving a auth request to the server, in the /var/log/radius/radiusd.log file, I get the following line whenever the auth request comes though. ---- Mon Feb 19 12:29:46 2007 : Error: Invalid operator for item User-Password: reverting to '==' ---- If anyone could point me in the direction of a document or manual on how i could fix this, would be appretiated, i checked the man pages but dont see anything specific there towards my problem, and well to be honest I just dont seem to be able to find a relevant document for FreeRadius on this error. Any help would be appretiated. Kind Regards - Marc
