Sarosh,

Scroll towards the bottom of the config file and set the SecurityDatabaseKey value to the database key of the database that contains your security tables (such as User, Role, Security).

For example:

<add key="SecurityDatabaseKey" value="Northwind" />

This should point to a database key specified in the node of your config file. For example:

<databases>
  <add key="Northwind\Connection" value="server=(local);uid=sa;pwd=;database=Northwind;" />
  <add key="Northwind\DataAccessClass" value="DataAccessSql" />
</databases>
