Alfresco 4.2 Logout issue Siteminder

[g_rathod]

Team,

We are using alfresco enterprise 4.2.x

we have 4 different nodes 

e.g.   Alfresco-01

              Node101

             Node102

      Alfresco-02

             Node201

            Node202

I am able to login and logout successfully in Alfresco-01 , now problem is Alfresco-02 able to login but it is not able to Logout , when I click logout it stay on same page and when I check inspect element via chrome browser I am able to see below

Also below

I verified httpd.conf for all 4 node that is matched and OK.  what should be the issue here then.

It is not going to logout page.

Ideally while clicking logout

should give me output like below

Looks like you are simply being reauthenticated by SiteMinder against Alfresco. The logout action in Alfresco will only kill the HTTP session but may not kill the already authenticated SiteMinder session. Since I do not know how SiteMinder is integrated in httpd and what configuration properties would be relevant, I cannot give any pointers...

Strange thing is Alfresco-01 is successfully authenticated and worked fine with logout action, while  problem is with alfresco-02

I check and compare all files required   ( httpd.conf / ssl.conf )
