  Read doc/Simultaneous-Use, Section 3.  It documents what happens for
Simultaneous-Use to work.

  Go check it against the debug output.  Run "radwho" after the first
login to see if FreeRADIUS has recorded that the user has logged in.

  If that information isn't recorded, Simultaneous-Use won't work.
Don't blame FreeRADIUS.  Blame the NAS which is sending useless data.
