Symptoms

RADIUS Authentication fails when the logon name contains non-ASCII characters. The problem is caused due to failure in conversion from UTF-8 to Windows-1252.

Impact

Users are not able to log in.

Conditions

RADIUS authentication is configured and username/password contain non-ASCII characters.

Workaround

There is no workaround for this issue.

Fix Information

Now it is possible to configure charset decoding behavior. You can decode usernames and passwords into CP-1252 (original behavior) or use UTF-8 charset (in this case, RADIUS Auth sends the username and password unmodified).
