We have a team site and I used an email enabled AD group to provide membership. This was for student elections, class of 2014. When the students logged in, some were fine but some called and were getting access denied errors. When I look at those students portal pages, the team site is not showing on their web part. If I add them in directly they can get in. Is there an issue between sharepoint and AD where it doesn't see all the members in an AD group? This same thing happened when we added students to the portal, some could logon and some could not with access denied. Help!!!

For the users that can't get in, were they recently added to the AD group? Can you verify that they are in the AD group?Planet Technologies || SharePoint Task Force
