To configure Domino servers to be AUT servers, configure TLS on the servers and then create a Configuration document for the AUT servers.

1. Setting up TLS on AUT servers
HCL Notes clients connect to AUT servers over secure HTTPS connections. Before you configure AUT servers, complete this procedure to create an TLS certificate on AUT servers.

2. Creating a Configuration document for AUT servers
After you set up TLS on the AUT servers, create a group for the AUT servers in the Domino directory and then create a Configuration document that is associated with the group. The Configuration document enables the servers for AUT and specifies a server DNS (an AUT server or a round-robin DNS name) that Notes clients connect to check for updates.
