This is now fixed. The downloads have 4.23-2 packages with a fix for %W 
formatter that was causing the problem. It was caused by updates which 
allow Radiator to run with maximal warnings in which case care needs to 
be taken to, for example, not to split undefined User-Name to realm part.

While the function it tried to call had a test, actual %W formatter did 
not have, but it now has.

This can happen, for example, when a RADIUS client switches to a 
secondary RADIUS server because of, for example, timeout from the 
primary. In this case the secondary gets an EAP message that is part of 
ongoing EAP authentication but it has no means to continue. In other 
words, it has no state that is needed for the authentication.

Changes in 4.23 should not have changed EAP handling. Could you try with 
with 4.23-2 package to see that it's not releated to problems caused by 
the %W problem.
