Hi Heikki,
EAPAnonymous is set back to %u and EAPType is set to MSCHAP-V2
Now, indeed, the user-name/identity is found in the users-file, and is found in
the LDAP-server, but now failed on EAP MSCHAP V2 (no
such user???)
This has, I think, something to do that mschapv2 needs for challange and
responce the whole username including the realm. This works
with 'NoEAP', but not with EAPType MSCHAP-V2.
