It's recommended to have a PAM Framework Manager on UNIX/Linux. You can have 1 PAM Manager for both rdprelay and ssh relay if it's UNIX/Linux. It can support both Windows and Unix/Linux connections. A Windows Framework Manager server will not be able to have the sshagnt module installed and SSH Account Domains will fail to be created. Please see TID 7017922 for further details of a potential scenario that would happen if you desire to manage SSH UNIX/Linux hosts with just a Windows Framework Manager.
