# Overview

The data source configuration files need to be modified so that Wildfly knows where to find the database(s) associated with each cell. All other configuration information has been moved to the database (in a table called HIVE_CELL_PARAM) as of 1.7.12. 

Click on the individual cells on the navigation tree on the left or the links below to see information on configuring each cell.

## A Note on Using Active Directory in SQLServer

If you are using SQL Server, it is possible to use Active Directory accounts for the database users (i.e., Integrated Login). To enable this, replace

`jdbc:sqlserver:``//localhost:1433`

`with `

jdbc:sqlserver://localhost:1433;IntegratedSecurity=true;Trusted_Connection=Yes>

Then the password field in the  section will be ignored and the SQLServer integrated security will be used.
