SharePoint and MySQL server

Hi,

I have a development server with different stuff installed. Among other it has several MS SQL instances and 1 MySQL instance (port 3306).

I try to install SharePoint there and use MS SQL instance on default 1433 port, setup and configuration wizard succeed but when I try to open Central Administration I get MySql.Data.MySqlClient.MySqlException.

I tried to setup SharePoint 2010 and 2013 and both have the same problem.

In 2010 the error looks like this:

"SharePoint Foundation Runtime Unexpected System.Configuration.ConfigurationErrorsException: Authentication to host '' for user '' using method 'mysql_native_password' failed with message: Access denied for user''@'my.server.com' (using password: NO)"

In 2013 there are more details:

"SharePoint Foundation Runtime Unexpected MySql.Data.MySqlClient.MySqlException: Access denied for user''@'my.server.com' (using password: NO)    at MySql.Data.MySqlClient.MySqlStream.ReadPacket()     at MySql.Data.MySqlClient.Authentication.MySqlAuthenticationPlugin.ReadPacket() 81e05d9d-278c-00a9-0000-022d6f4815c6

SharePoint Foundation General High Getting Error Message for Exception System.Configuration.ConfigurationErrorsException: Authentication to host '' for user '' using method 'mysql_native_password' failed with message: Access denied for user''@'my.server.com' (using password: NO) (C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config line 287) ---> MySql.Data.MySqlClient.MySqlException: Authentication to host '' for user '' using method 'mysql_native_password' failed with message: Access denied for user ''@'my.server.com' (using password: NO) ---> MySql.Data.MySqlClient.MySqlException: Access denied for user''@'my.server.com' (using password: NO)     at MySql.Data.MySqlClient.MySqlStream.ReadPacket()"

To prevent misunderstanding: I DO NOT use MySQL instance during SharePoint setup/configuration in any way. I create farm in MS SQL instance. Configuration and CA content databases are both created successfully in that MS SQL instance.

What should I do to make SharePoint NOT connecting MySQL?
