I'm not really sure how to short and precisely describe my problem. Thus, I was unable to find a solution or at least a hint via google.
We have a Microsoft AD domain and are currently planning to use an external developed software on a third party managed server. It is planned to utilize our AD for authentication and authorization, but our information security department does not like the idea of opening our firewall for ldaps, ldap-ssl and kerberos for access through the third party managed server.
My question is: Are there other , ore secure ways, to utilize our AD for authentication and authorization?
Thanks in advance, PJ
