I have only one SIP domain in my deployment, yet when I go to enable a new user in the Control Panel, the SIP domain fields under "Generate user's SIP URI" are all blank. I need to click the pull-down and select from the only option there is.
Lync has a "Default" SIP domain. The CSCP should populate the SIP domain fields on the form with this value automatically.
Should the developers see reason why this shouldn't happen in a deployment where there are multiple SIP domains, it should at least be pre-selected for us when a deployment has only the one to choose from.
