When you create a Site, you specify the user database authentication method. You cannot change the authentication method after you have created a Site, however, if you need to change the authentication options, you can do so from the Site Options tab. The options available in the Authentication Provider Options dialog box change depending on which authentication method the Site uses.
To edit the authentication options for a Site
In the Administrator, connect to EFT Server and click the Server tab.
In the left pane, click the Site you want to configure.
In the right pane, click the General tab.
Next to the User auth manager box, click Configure. The Authentication Provider Options dialog box appears.
To specify that the user list is to be updated automatically, select the Enable Automatic Refresh every check box, then specify how often you want EFT Server to check the authentication database for new users. Clear the check box if you do not want the Site's user list to refresh automatically. (You can also manually refresh the Administrator to see any changes (View > Refresh User Database).
In the text box, edit the connection string, as needed. Refer to Using a DSN-Less Connection with ODBC Authentication for details of how to create a connection string depending on the type of database to which you are connecting.
Click OK to close the dialog box.
Click Apply to save the changes on EFT Server.
