We have two Nutanix file instances, SiteA-ntxfiles1 and SiteB-ntxfiles1, configured for Nutanix Files VDI Sync. We have a set of Citrix VDAs running file based Citrix UPM at SiteA and SiteB configured for their respective Nutanix file instances. Also configured are Windows redirected folders to their site specific Nutanix file instances. Both user profiles and redirected folders have their own Nutanix file shares and both shares are configured for VDI Sync. To test, we log in to a SiteA VDA as a new user and the user profile and redirected folders appear to create and map correctly. We log out of the VDA at SiteA and wait for VDI Sync to finish it's current sync and wait another 10 minutes for it to sync again. We log in to a SiteB VDA and either experience redirected folders that do not map and appear to be locked or receive a local user profile. The problem isn't exclusively with SiteB as we sometimes experience successful profile and folder mapping in SiteB but are unsuccessful in SiteA. At times we've watched the Windows File Share open connections and open files and made sure they were gone and still experienced problems logging in to either SiteA or SiteB.
