We're using Sharepoint Online (Office365/OneDrive for Business) to share files between different groups of users. We have a Sharepoint group with a nested Active Directory group associated and the Sharepoint group is given read/write permissions to the
items, but the users can't access them. If the AD-user or the AD-group that the user is in, is added explicitly to the item permissions instead of through the Sharepoint group, it works, but I'd rather not go that route since we already have lots of items
with the Sharepoint group permissions configured.
The AD-group is a nested group itself, if that helps. Although I have stumpled upon a few people that mention nesting AD groups might be an issue in itself, but I can't really find any documentation to support that claim.
Office365 is integrated with an on-premise ADFS server, which has recently been upgraded from ADFS 2.0 to 3.0 - not sure that's the cause of the permissions issue, but something could have happened during that migration. It was definitely working at some point in the past before the upgrade.
