I set up a team site which I manage access to it using an AD group. Whenever a new hire comes to the company, his user name is added to the AD group. The first time a added the group to the members of site, all users in the group got access. However, the new hires are not given access. The user list does not get refreshed by SP.
It's worth it mentioning that adding the user manually gives him access to the site.
Am I missing a config step in here?
My IT support team tested with another AD group and site. It worked. It looks like the issue only happens in this team site.
