When an Active Directory authentication service has been configured, it is possible to enable single sign on with Kerberos for Windows users of SuperCROSS and the SuperADMIN console.

This means that users can log in to SuperCROSS automatically based on their Windows login credentials, without them having to specifically enter a username and password.

Single Sign On with Kerberos is only supported when SuperADMIN is running on Windows.

There are a number of steps required to set up single sign on:

Step 1 - Activate Single Sign On in SuperADMIN

The first step is to configure your authentication service in SuperADMIN.

Once you have set up authentication, you need to enable Kerberos using the following command (replace <service_name> with the name of your authentication service):

auth <service_name> useKerberos true

Once Kerberos is enabled, the console will automatically start using it. You will be able to log in to SuperADMIN in future simply by using the login command without any arguments:

login

If Kerberos is working, you will be immediately logged in based on your Windows credentials and will see a message similar to the following:

user <your-windows-username> logged in

If Kerberos is not working, you will be prompted to enter a username and password.

To login as a different user when Kerberos is enabled, you must specify the alternative username and password with the login command:

login <other-user> <other-user-password>

The SuperADMIN  console will automatically attempt Kerberos authentication when it is enabled on the server. However, by default, it will attempt the standard SuperADMIN authentication first, requiring a username and password to be entered before proceeding to try Kerberos.

To give preference to Kerberos authentication, increase the priority of the Kerberos-enabled authentication service. For example:

auth <service_name> priority 200

Step 2 - Enable Single Sign On in the SuperSTAR Clients

Some additional configuration is required in order to use single sign on with the SuperSTAR clients.

SuperCROSS

To use single sign on with SuperCROSS, you need to make the following changes on every machine where SuperCROSS is installed:

  1. Close SuperCROSS if it is running.
  2. Open the ssii.ini configuration file in a text editor (by default this is located at C:\ProgramData\STR\SuperCROSS\Catalogue\ssii.ini).

  3. Add the following lines to the end of the file:

    [SingleSignOn]
    SSODLL=SSPI_Kerberos.dll
  4. Save the file and restart SuperCROSS.

  5. Select File > SuperADMIN Connection.

    The SuperADMIN Connection dialog displays.

  6. Select the Automatic sign-on using Windows credentials (Kerberos) check box:

  7. Click OK.

You can now connect to databases as usual without needing to provide any credentials.
