Issues with mysql and logmysql passwords

If the wiki link below does not work then please follow these steps:

http://wiki.zimbra.com/index.php?title=Resetting_LDAP_%26_MySQL_Passwords

Issue:

Due to wrong passwords in the database mysql/logmysql is not able to connect to the database with the existing password.

We need to change the passwords manually.

Error:

   #logmysql 
   ERROR 1044: Access denied for user 'zimbra'@'localhost' to database 'zimbra_logger'

   #mysql
   ERROR 1044: Access denied for user 'zimbra'@'localhost' to database 'zimbra'

Steps:

1) For Mysql:

a) Stop the mysql service. [Run as Zimbra: mysql.server stop]

b) Run as ROOT vi /opt/zimbra/bin/mysql.server

c) Modify the following:

     --defaults-file=${mysql_mycnf} \
     --external-locking \
     --ledir=${mysql_directory}/libexec < /dev/null > /dev/null 2>&1 &
  TO
     --defaults-file=${mysql_mycnf} \
     --external-locking \
     --ledir=${mysql_directory}/libexec < /dev/null > /dev/null 2>&1 --skip-grant-tables &

Save and Exit the file. d) Start the mysql service. [Run as Zimbra: mysql.server start]

e) Connect to the database.

   # mysql
   Welcome to the MySQL monitor.  Commands end with ; or \g.
   Your MySQL connection id is 6883
   Server version: 5.0.45-log Source distribution
   Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
   mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';      ----> Root user.
   mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='zimbra';    ----> Zimbra user.

Make sure the 'password' you specify is should be same as zmlocalconfig -s | grep mysql_root_password and zmlocalconfig -s | grep zimbra_mysql_password.

   mysql> FLUSH PRIVILEGES;
   mysql> exit

f) Go back to the file remove the --skip-grant-tables and save and exit the file.

g) Stop and start the mysql service. [mysql.server stop and start]

h) Now try to connect to mysql.

2) For Logmysql:

a) Stop the logmysql service. [Run as Zimbra: logmysql.server stop]

b) Run as ROOT vi /opt/zimbra/bin/logmysql.server

c) Modify the following:

     --defaults-file=${logger_mysql_mycnf} \
     --external-locking \
     --ledir=${logger_mysql_directory}/libexec &
   TO
     --defaults-file=${logger_mysql_mycnf} \
     --external-locking \
     --ledir=${logger_mysql_directory}/libexec --skip-grant-tables &

Save and Exit the file.
