Output List of User's Groups

Use PowerShell!

$user = [wmi] "Win32_UserAccount.Name='JohnDoe',Domain='YourDomainName'"
$user.GetRelated('Win32_Group')

or only for group names:

$user = [wmi] "Win32_UserAccount.Name='JohnDoe',Domain='YourDomainName'"
$user.GetRelated('Win32_Group') | Select Name

Hmm.

net user paul /domain | find "Global Group memberships"

Will give you the the groups, but if you don't want the header you'd need something more involved:

for /f "tokens=4*" %f in ('net user paul /domain ^| find "Global Group memberships"') do echo %f

So %f contains the groups.

dsquery user -name "My Full Name" | dsget user -memberof | dsget group -samid

I found this pretty much gives me what I was looking for, in case anyone was curious! :)
