Background:

I made an upgrade on SSO Server 1  from 10.1.2.x to 10.1.4.x ,while for SSO Server 2, I kept the older version. Here is the version number comparison that you could easily found out from the setupinfo.txt under the software installation folder.

and then I tried to register the same partner application server with the same syntax I used to write on SSO Server 2 like below:

It actually gave me no complaint on the SSO Server 1.However, when I transfered the osso.conf file to my partner application server and put it under the same directory I used to. After restarting the HTTP Server, I got the following error: SSO server version v3.0 is not supported.

Solutions:

This is caused by a version mismatch in the SSO conf file I generated from my SSO Server 1. The SSO version was 10.1.4.0.1 as you could see above and I was using the generated conf file for my partner application of a version 10.1.3.4.1 like below:

.     By default, using the same syntax for registering the partner application server on Server 1 would create an osso.conf file of a version 3 which is a higher version that is not compatible with our partner server. In order to solve the problem, we have to explicitly tell the SSO Server to generate a lower version file by giving an extra parameter specifying this need. So the new syntax would look like:

After restarting the HTTP Server, it worked perfectly with the new file! Good luck!
