Get list of AD groups a user is a member of
Solution 1:
You can do this in PowerShell pretty easily. I'm sure you can do it with the ds tools too, but they're old and crusty and PowerShell should be used for everything possible nowadays.
Import-Module ActiveDirectory
(Get-ADUser userName –Properties MemberOf | Select-Object MemberOf).MemberOf
Shorter version
(Get-ADUser userName –Properties MemberOf).MemberOf
Solution 2:
Or with the net user command...
net user /domain username
