Error loading HTTP task 'Single Sign-On configuration is invalid'

Technote (troubleshooting)


Problem

In Lotus® Domino®, you configure Single Sign-on (SSO) for all servers in your domain. When you load the HTTP task on a server, you are presented with the follwing error message:

      "Single Sign-On configuration is invalid".

Cause

Multiple SSO documents with the same name.

Diagnosing the problem


Log extract:

09:12:21 HTTP Server: Restarting
09:12:29 HTTP Server: Error loading Web SSO Configuration 'LtpaToken' (Single Sign-On configuration is invalid)
09:12:32 HTTP Server: Restarted

From examining the server names.nsf, there are two SSO documents with the same name "Ltpa Token".


Resolving the problem

With multiple SSO documents, there must be different names for the tokens or you must have a specific Web server configuration for the server.


Example:

1. Web SSO from Internet Sites view. From the Domino Administrator, click Configuration > Web > Internet Sites.This shows the use of the Organization field populated with a group name.
2. In the Server document, "Load internet configurations from Server\Internet Sites documents" field is set to Disabled.
3. The Organization field should be blank if "Load internet configurations from Server\Internet Sites documents" is set to Disabled.
4. An entry is required only when the "Load internet configurations from Server\Internet Sites documents" field is set to Enabled. This server should not be included in this token or set to Enabled for "Load internet configurations from Server\Internet Sites documents" in the server.
