win32utils devel - Mar 2009 - Getting a list of groups for a given user

Hi,

How does this look for finding a list of groups for a particular user?

This is for the sys-admin library. Assume "self.name" is pretty much
the same thing as Etc.getlogin would return.

# admin.rb
Class User
   def groups(domain=nil)
         host = Socket.gethostname
         cs = "winmgmts:{impersonationLevel=impersonate}!"
         cs << "//#{host}/root/cimv2"

         begin
            wmi = WIN32OLE.connect(cs)
         rescue WIN32OLERuntimeError => err
            raise Error, err
         end

         if domain
            query = " select * from Win32_GroupUser where partcomponent =
"
            query <<
"\"Win32_UserAccount.Domain=''#{domain.upcase}'',Name=''#{self.name}''\""
         else
            query = " select * from Win32_GroupUser where partcomponent =
"
            query <<
"\"Win32_UserAccount.Domain=''#{host.upcase}'',Name=''#{self.name}''\""
         end

         array = []

         wmi.execquery(query).each{ |groupuser|
            array <<
groupuser.GroupComponent.split(''='').last.tr(''"'',
'''')
         }

         array
      end
end

Regards,

Dan

Nevermind this. It was easier to use the IADsUser interface:

adsi = WIN32OLE.connect("WinNT://some_domain/some_user")
adsi.groups.each{ |g| p g.name }
