Connect external MySQL Databaser to Owncloud?

Hi I am trying to setup Owncloud with an external MySQL DB.

In MySQL server - I have changed bind-address= , created a user and granted , flushed privileges.

Now i am able to connect to MySQL from CMD in Owncloud server.

When I try to setup getting an error
" Error while trying to create admin user: Failed to connect to the database: An exception occured in driver: SQLSTATE[HY000] [1044] Access denied for user ‘oc_root2’@’%’ to database ‘owncloud’ "

Can some one please help.
