Submitted:	1 Aug 2005 20:04	Modified:	25 Aug 2005 12:44
Reporter:	Dean Ellis
Status:	Closed
Category:	Server	Severity:	S2 (Serious)
Version:	4.0.26 forward	OS:	Linux (Linux)
Assigned to:	Jim Winstead	Target Version:

Description:
If a host is listed in /etc/hosts, and a login is created for user@ip or user@alias
(rather than user@domainname), for a non-localhost IP, that user is unable to set password
for self.

How to repeat:
Equivalent of:

In /etc/hosts:

10.0.0.10 testserver ts

GRANT USAGE ON *.* TO testuser@'10.0.0.10';

connect as above user, verify the connection:

SELECT CURRENT_USER();

try to set password:

SET PASSWORD = '';

Receiving: "Can't find any matching row in the user table."

Login of testuser@testserver is able to change password.
Login of testuser@ts is unable to change password.

Suggested fix:
