we have two Domaincontrollers (2012 R2, 2016 - will be replaced next week with 2x 2022, Domain Level yet 2012, will be 2019), all Users are synced to MS365 via AAD Connect.
All of our new clients are AzureJoined only and managed by intune, not directly joined to the local Active Directory. Users are login into their devices via UPN email address removed for privacy reasons . I'm trying to mount some network shares with the users UPN email address removed for privacy reasons which are provided by the Domain Controller. Unfortunatly this isnt working somehow, and i don't know why. If i login manually or via powershell with the pre-windows 2000 login def\abc everything is working.
anybody here who can help to give my intune managed clients access to the network shares via UPN?
