ERROR 1045 (28000): Access denied for user (using password: YES) - mysql

Question

I am trying to have a simple mysql Database on a server and another database on another server that connects to it.
I have done the following :
Installed mysql-server
Created the database
Created the user with :
CREATE USER admin#'localhost' IDENTIFIED BY 'admin';
Given the privileges to this user with :
GRANT ALL PRIVILEGES ON confWeb.* TO admin#'';
Opened the bind-adress
Now when I launch the command mysql -u admin -p -h <address> from another server, it just tells me again and again :
ERROR 1045 (28000): Access denied for user 'admin'#'X.X.X.X' (using password: YES)
I really have no idea what to do at this point. I think I've tried everything.
I tried putting GRANT OPTION in the end of the GRANT line, I tried allowing a lot of different addresses but nothing worked.

Answer 1

In MySQL, a user is identified by both user and host.
This user:
admin#localhost
is not the same user as
admin#'10.242.167.235'
As one option, you could do this to allow connection:
GRANT USAGE ON *.* TO admin#'10.242.167.235' IDENTIFIED BY 'mysecret' ;
GRANT ALL ON confWeb.* TO admin#'10.242.167.235' ;
For a longer discussion of the MySQL Access Privilege System, including "wildcards", the special meaning of localhost, using IP addresses instead of hostnames, etc.

I do not really know why, but appareantly, it worked when I used the with grant option and first gave access to the database, and then to its tables.
Here is the list of commands that I entered :
mysql> create user 'admin'#'localhost' identified by 'admin';
mysql> grant all privileges on confWeb to 'admin'#'10.69.101.%' identified by 'admin' with grant option;
mysql> grant all privileges on confWeb.* to 'admin'#'10.69.101.%' identified by 'admin' with grant option;
mysql> flush privileges;
Again, I don't really know why it didn't work before and the answers that I saw look like all the documentation I have seen but it looks my problem was somewhere else.

Use following step:-
CREATE USER 'user name'#'IP or % or localhost' IDENTIFIED BY 'password';
GRANT all privileges ON *.* TO 'user name'#'IP or % or localhost' IDENTIFIED BY 'password' ;
flush privileges;
Here in the place of "IP"; you use remote server ip where you want to connect the server.You can also use "%" for useage databases from any plcae in the world.
Now, in Grant option; In the place of "all privileges" you can given access seperately like as select,alter,update etc.
