Is it possible to configure LDAP over two sided SSL between IBM WebSphere Application Server and MS ActiveDirectory? I can not find any confirmation, it is possible or not to implement.
I am not sure about the ActiveDirectory part but for the WebSphere part:
When you add the repository to check Require SSL communications, then you select Use specific ssl configuration
When you click SSL configurations you can create a new configuration and provide both server and client certificates there.
Once you do that it should do two sided SSL verification.
