Use the snippet below to get a list of all AD groups that a certain username is member of. Replace “[username]” with the correct username. Execute this command in a new Powershell window.
Get-ADPrincipalGroupMembership [username] | select name
You should get the following response:
PS C:\Windows\system32> Get-ADPrincipalGroupMembership svc_myapp | select name name ---- Domain Users Service_accounts
Good luck!
