Hi guys,

I have a primary write server (server1) which replications to two servers (server2 and server3) which are query servers. I am replicating all databases to these servers including the MySQL database.

When i execute a GRANT as follows replication works perfectly..

GRANT execute,select ON database1.* TO `user1`@`host` IDENTIFIED BY 'password';

However if i did the same GRANT to alter permissions on an existing user without IDENTIFIED clause replication breaks..

Error 'Can't find any matching row in the user table' on query. Default database: 'mysql'. Query: 'GRANT execute,select ON database1.* TO `user`@`host`'

If I try and run the query manually i get the same error..

Server 1:

mysql> SHOW VARIABLES LIKE "%version%";                                                                           
+-------------------------+------------------------------------------------------------+
| Variable_name           | Value                                                      |

    [mysqld]

    socket=/var/lib/mysql/mysql.sock
    user=mysql

    log-bin = /var/lib/mysql/logs/borg-binlog.log
    max_binlog_size=50M
    expire_logs_days=7

    basedir=/var/lib

    [mysqld_safe]
    log-error=/var/log/mysqld.log
    pid-file=/var/run/mysqld/mysqld.pid

Server 2:

mysql>  SHOW VARIABLES LIKE "%version%";
+-------------------------+------------------------------------------------------------+
| Variable_name           | Value                                                      |

| version                 | 5.0.77-log                                                 | 

my.cnf

server-id=12

Thanks for taking a look


Edit: Currently its running fine, until you do the grant which breaks it...
