Description

initialize.sh causes access denied error if DB server is seperated from MCF's.

Suppose each server's IP are like followings:

MySQL Server IP: A
MCF Server IP: B

and properties.xml has the follwing parameters and values:

 <property name="org.apache.manifoldcf.databaseimplementationclass" value="org.apache.manifoldcf.core.database.DBInterfaceMySQL"/>
 <property name="org.apache.manifoldcf.dbsuperusername" value="root"/>
 <property name="org.apache.manifoldcf.dbsuperuserpassword" value="<password>"/>
 <property name="org.apache.manifoldcf.database.name" value="manifoldcf"/>
 <property name="org.apache.manifoldcf.mysql.server" value="A"/>

Then, executing initialize.sh causes the follwing error:

Caused by: java.sql.SQLException: Access denied for user 'manifoldcf'@'B' (using password: YES)

The problem is that MCF requests MySQL to create a new "manifoldcf" user with localhost access.
In this case, of course, MCF is on the server with IP B, MySQL should create a new user with IP Address B.

The following method is the one creating a new MySQL user in the user table.
Modifying the part where IP information is added solves this problem.

JAR NAME :mcf-core.jar
PACKAGE :org.apache.manifoldcf.core.database
CLASS NAME :DBInterfaceMySQL
METHOD NAME: public void createUserAndDatabase

            if(userName != null)
                try
                {
                    list.clear();
                    list.add(userName);
             //     list.add("localhost");
                    list.add(IP_ADDRESS_B);
                    list.add(password);
		     ...
		     ...
		}

I guess it would be nice if properties.xml can have a new property taking MCF server IP to
have MySQL create a "manifoldcf" user with that IP.
