Description:
I'm not sure if this is a bug, but is it a problem when you grant a user in a server IP and in the same IP with just wild card in the end? I just encountered that today and it's really weird that the user cannot connect but when we removed the IP (w/out wild card it works).

 GRANT USAGE ON *.* TO 'user'@'192.168.3.%' IDENTIFIED BY PASSWORD 'XXXXXXXXXXX |
| GRANT SELECT, INSERT, UPDATE ON `db`.* TO 'user'@'192.168.3.%'

AND

GRANT USAGE ON *.* TO 'user'@'192.168.3.10' IDENTIFIED BY PASSWORD 'XXXXXXXXXXX |
| GRANT SELECT, INSERT, UPDATE ON `db`.* TO 'user'@'192.168.3.10'

How to repeat:
Create the same user name with a grant on IP only and the same IP with wild card in the end.

Suggested fix:
Deleted the user that is granted on the IP without wild card and it works.

Hi,

So far, I am not able to repeat the behavior, so I have two questions:

* Is '192.168.3.10' the real address of the host. This looks like a dynamic IP, so, please, can you re-check whether the address is exactly like the one for which privileges are granted

* Check with latest, or near-latest version of 5.6
