Work with clear password , but not with MD5 ( but both work with radtest)

[webmaster at techshop-lille.fr]

Hello !

I'm using Freeradius 2.1.12 with mysql Backend and a Ubiquity/Unify network for authenticating my wireless users

Actually it work fine with users in Sql DB with User-Password := value

Off course i wanted to change it for a MD5 version

So i changed User-Password with MD5-Password

Radtest is working fine , with both users using the MD5 and Clear Text password , replying me with auth and VLAN ID

but when i try to authenticate with real world Wireless users , only the users with clear text password are working

the test users with MD5 password only work with radtest
I've parsed the log , and here is what seem to be different from real world vs radtest :
--------------------
