CSCin63049—Incorrect behavior on failed LEAP authentication

If LEAP authentication fails because the authentication server is down, a message appears indicating 
that the LEAP authentication timeout has expired. When you click OK, you are prompted to re-enter 
your user credentials even though the failure was caused by the authentication server and not 
improper credentials.

CSCec39604—EAP-TLS authentication attempts fail for users with zero-length passwords

EAP-TLS authentication attempts fail for users with zero-length passwords. To work around this 
issue, set up a Windows password that contains at least one character.
