radius+mysql weird problem

[Jorge Minassian - Comintec]

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.
