on our test environment, user profile service was not working. When we checked, there was no connection between AD and SharePoint. And also "Forefront Identity Manager Synchronization Service" was not started on Services and "User Profile Synchronization service" was stopped status on Central Administration.
for resolving issue, we think, we need to create connection between them. But our questions, can we give same domain connection which are using on Production environment? Means for example on Production, we had given connection with "Google" domain. So Test environment also same "Google" domain with same service account can we create connection? (or) is there any effect on Production if we use same domain connection on Test environment?
After making connection, Forefront Identity Manager Synchronization Service and User Profile Synchronzation service will be start?
is there any other process do we need to follow?
