Okay.

Generating my password with :

htpasswd -nd plemelin ( crypt )
and setting the attribute to crypt-password in mysql did the trick.

Generating the password with :
htpasswd -nm plemelin ( md5 )
and setting the attribute to MD5-password doesnt work.

I think i did enough radius for the week.

Thank you Alan, with your pointers I learned a great deal.
