title: Determining User's role in a SharePoint site/workspace using the webservices API
body: <p>How do I figure out the role(s) of a user in a site using the webservices API?  All I have to go on is the username and domain.</p>
  
  <p>I've found that the PermissionsService.Permissions.GetPermissionCollection(url,"Web") will return a collection of permitted users and groups with their permissions masks but I still need to figure out if the user is in any of the groups and then convert the permissions masks into a roles collection.</p>
  
  <p>I feel like there's a better way to do this and I'm just missing it.</p>
