[dovecot-cvs] dovecot/src/pop3-login client-authenticate.c, 1.50, 1.51

[cras at dovecot.org]

Update of /var/lib/cvs/dovecot/src/pop3-login
In directory talvi:/tmp/cvs-serv13054/pop3-login

Modified Files:
	client-authenticate.c 
Log Message:
IMAP: Reply with tagged BAD if authentication is aborted because client sent
"*" or something else that was a client error.

If authentication failed for any reason, the error message was always
"Authentication failed". In case of client errors or if auth process gave
an error message, it should have been that instead.
