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 EFT Administrator, connect to EFT Server and click the Server tab.
In the left pane, click the Site that you want to edit.
In the right pane, click the Site Options tab, then 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.
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 save the changes.
