I have a 2008 server running active directory and Sharepoint Foundation with Sql server express 2008. There are only 80 users in the organization, so everything is on one box. We have a fairly simple sharepoint site with about 6 sites within it. We have set each of the sub-sites not to inherit permissions so that we can give access to certain users for those sub-sites.
Thats all straightforward, but here is the odd thing.
Let's say I have a sub-site called "senior managers". On the permissions for that site I have added the Active directory group called "senior managers". Within that group I have 4 members. When those members logon, they cannot get access to the site. When I check permissions for their users names, Sharepoint says they have no access, even though the group they belong to does have access.
It is as though Sharepoint is not able to read all the users that belong to the AD group. To make it worse, on some of the other sites, it reads some people, and some it does not. It does not seem to have a complete update of active directory. If I create a Sharepoint Group and add the users to that group, it all works.
Any thoughts? Thanking you all in advance.
