Re: Adjusting user connection settings to the Sametime Proxy Server

in Step 3, you need to click on the Deployment Identifier for the server in order to proceed, not the Edit button.

This may be different for a cluster; I do not have a cluster to test this scenario, but for a single server deployment this is the corrected Step 3 process.
