radius+mysql weird problem

Hello all !,

After upgrading Fedora from FC2 to FC4, I got what is described below from
log (radiusd -X)
If I query database manually, I get all info about users (all users are
correctly on DB), but radius still says "No matching entry in the database
....".
If using "files", it works OK.
I tried to downgrade DB (from 4.1 to 3.23), also reinstal freeradius from
rpm or compiled by me, but problem persists.
Have someone any ad about this ?.
I will apreciate any help to troubleshoot this problem !.

Thank you very much,
Jorge.
