We have a group of active directory users use Sharepoint 2003 ASP.NET hosted application. The application checks for specific roles for the logged-in users. However, for some reason when the application check for a specific assigned role in some users, the roles can't be found. The roles are assigned to theses users, so we expect to find it when we check for the user roles.
Are there any suggestions to the reasons that may cause these roles to be inaccessible for some users? Is there any way to force refreshing the users' roles in case it's a caching problem as we think it may be a caching issue?
