I have a SharePoint 2010 production environment and I'm experiencing unusual behaviour with the Check Permissions form.
I know that a user has access, but the Check Permissions form is not reporting that they have access.
The user is a member of an AD group (and not through deep nesting).
The AD group is a Global group, not a Universal group.
Other members of the same group are being correctly identified using the Check Permissions form.
My development environment is correctly identifying this user as a member of this group.
This is a single domain environment.
The user was added more than 24 hours ago and appears to be on all of the domain controllers, so its not a replication issue.
The ULS files don't show any errors or warnings against the chkperms.aspx's correlation id.
Anyone else seen this? Suggestions?
