NetUserGetLocalGroups

I am facing issue with the windows API NetUserGetLocalGroups ( used the

LG_INCLUDE_INDIRECT) and NetUserGetGroups to get all the groups the user

belongs too. But for some reason I end up getting only the top level

information and all the nested information to which the user belongs too.

Ex:

Group Name: VM1WIN2K31\Administrators

Group Name: VM1WIN2K31\None

I have tried other option by setting up the security context ( which

involves user name and password) on client side and using this information

on the server side and from GetTokenInformation I am able to retrieve all the

information.

Ex:

Group Name: VM1WIN2K31\Administrators

Group Name: VM1WIN2K31\None

Group Name: VM1WIN2K31\Everyone

Group Name: VM1WIN2K31\Users

Group Name: NT AUTHORITY\NETWORK

Group Name: NT AUTHORITY\Authenticated Users

Group Name: NT AUTHORITY\This Organization

Group Name: NT AUTHORITY\NTLM Authentication

I know if I have the user name and password, I could user the LogonUser

context and then from the token I could get the information.

But the issue is I don't have the user password and how can I query all the

groups the user belongs too by just using the NetUserGetLocalGroups and

NetUserGetGroups API.

Could anybody throw some light on this one. Appreciate your help on this one.
