Access denied after adding Active Directory group to shared folder

Question

I'm trying to automate file sharing process and I started by creating some Active Directory groups for each permission:

USR_TEST_GROUP_RD, USR_TEST_GROUP_WR, USR_TEST_GROUP_FULL

I've added some Active Directory users to those groups and added those 3 groups to a folder for them to access, but I'm sill getting an Access Denied message. Why?

Answer 1

The users will have to log out and then log back in again to have their security token updated with the new groups. In a testing scenario like yours it's entirely possible that this wasn't done after the group add. When this happens you will experience exactly what you found out: access-denied errors when the permissions say they should be allowed.
