Yes sir, I am on version 7.0 update 70. The DNS and NTP settings on the NAS are pointed to our domain controller and the time looks to be identical between the two. Both the NAS and DC are on the same network/subnet and I can ping both directions using the FQDN. Question: I have tried all authentication methods and options with no luck. Our current domain function level is 2012 and I assume I should be using Windows ADS with IDMAP backend RID. Is this correct? Thank you!
