Hi
We've noticed an issue when using AD security groups to secure specific Sharepoint sites. Our problem arose when we created two AD security groups, say, SG-Main and SG-Sub with SG-Sub a Member of SG-Main. We then put a user account, eg Test1, into SG-Sub and secured a Sharepoint site to allow access to SG-Main. Test1 could then access the site - fine.
However when we then removed Test1 from SG-Sub we noticed that Test1's access persisted for the rest of the day. It was only when we tried again the following morning that finally Test1 was given an Access Denied message. Does anyone know what underpins this? Is there a way to force Sharepoint to refresh its 'knowledge' of the security group?
Thanks
