Within a freshly installed SharePoint 2013 farm (installed using (AutoSPInstaller) the initial Profile Synchronization is remaining in the Synchronizing status. I have tried both "SharePoint Profile Synchronization" as well as "SharePoint Active Directory Import" with no success. When using SPS I also have no status or activity in FIM UI. FIMSynchronizationService and Forefront Identity Manager Services are both running and have correct credentials. ULS log provides no negative information, and UPS related timer jobs are not creating errors. Also, nothing of significance in event viewer.
The sync has run overnight now at least twice with no success, I ended the process manually both times after at least 8 hours. (In the 2010 farm with same AD the full sync runs only 90 minutes.)
Any thoughts or ideas of where to troubleshoot this issue would be appreciated.
