Re: Get list of the Groups a User belongs to

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi,

On a Windows Server 2003 domain you can construct a WindowsIdentity by
passing in the user's name in the form, name@domain:

"WindowsIdentity(String) Constructor"
http://msdn2.microsoft.com/en-us/library/td3046fc.aspx

Then you can access the Groups property (2.0 framework only):

"WindowsIdentity.Groups Property"
http://msdn2.microsoft.com/en-us/library/system.security.principal.windowsidentity.groups.aspx

If you can't use the above solution since you are using a different version
of the framework or a different domain then I think you'll have to resort to
the unmanaged APIs such as LogonUser:

"LogonUser"
http://msdn2.microsoft.com/en-us/library/aa378184.aspx

The above will get you the User's token, which you can pass to the following
function:

"GetTokenInformation"
http://msdn2.microsoft.com/en-us/library/aa446671.aspx

Specify the value of TOKEN_GROUPS for the TokenInformationClass argument.

(Note that I haven't used these APIs myself)

You'll have to use P/Invoke for this, of course :)
