I have a Sharepoint 2016 (on premise) subsite which users are collaborating on a document with that isn't in a workflow. These users are added to the site programmatically to have contribute permission upon the site being created. However, when they try to access the document or the subsite itself, they receive an "Access Denied" error. Users are not granted permissions to the parent site, only directly to the subsite.

Upon looking at the permissions of the user on the site (Site Settings > Site permissions), the permission levels of the users appear as I would expect them to however, upon checking Check Permissions, most of the users are showing as having "None" permissions. A couple do appear to have Contribute permissions as I would expect.

The ULS log files don't show anything out of the ordinary during site creation. I see the site being created, the document being added and then the users being granted access as I might expect without any obvious errors but when they try to log in, the ULS file shows that their permission is 0x00000000 rather than 0x00010000, which I presume is Contribute permission in Sharepoint.

At this point, I am thinking it might be a database level problem but if that was the case, I would have thought that it would have caused other problems rather than this specifically. So why would Check Permissions show one permission level and the Site Permissions list show another?

  • If you manually add one of the users that has the permissions issue, what happens? I'm assuming you are using Powershell to do all this, there could be something up with how the script is looking up the users to add them to the site permissions. May 17, 2021 at 20:58

Generally speaking similar problems will not occur. I suggest you perform the following troubleshooting:

  1. Delete the wrong accounts, and then manually grant permissions to users/groups to see if similar problems occur.

  2. Whether the subsite has set unique permissions, and does not inherit the permissions of the parent site.

  3. Whether set unique permissions for documents or Document libraries.
