Bug Description
During the initial handshake, the server replies immediately to the incorrect user name with "Access denied". But if the user name is correct, but the authentication mechanism is not - like a short scramble, when a long one is needed, or a plugin should be used - the server might reply "try different auth plugin (or scamble length)".
This allows to detect what user accounts exists in the server.
Tested on 5.5.30-30.2 Percona Server (GPL), Release rel30.2, Revision 508
