you have a user in the system /etc/passwd with the id of 'omega'..and
theit password is not 'testing'

unix password takes priority over the plain users file....the debug output
very clearly shows this

by the way....i included this in the output because it clearly shows that this 
version of FreeRADIUS you are running has NOT been built with OpenSSL
support!  you must have the openssl-devel package installed and ensure the
build scripts build it!

the daemon got the RADIUS packet

'unix' module, which uses /etc/passwd , found this user.

'files' also found the user...but too late

CRYPT? why CRYPT? well, thats because its a /etc/passwd entry and not plain text
which the users file is.  passwords don't match. good. luckily they didnt
or you would have though all was okay..when in fact you werent reading the right file
at all
