Can you try to use different words to explain what's happening?
- Are you having an issue seeing an AD object (user, security group or computer) to pick for roles, entitlements, etc?
Or
- Are you having issues with outbound provisioning for an AD user (or group for provisioning) to a target App?
Two completely different problems with different troubleshooting approaches.
Remember, if you are a paying customer, you don't have to sit and wait for volunteers to answer in this forum. You are entitled to SLA-based standard or 24x7 support.
Otherwise, my advice is to study the Connector log and the help page for the topic in question.
