When adding another server to the multi-server setup, an invalid password error can occur. The error is misleading because it seems to imply that the wrong password is used.
However, it appears that this error appears when the external server's password does not fulfill the current server's password difficulty check. This should not be the case since the password on the other server should not be the concern of the current server and the multi-server setup should just accept whatever password it is given and do the connection.
