In Site Settings, Site Permissions, Check Permissions it tells me user A has Read access given through group X. IGroup X has Contribute to certain parts of the site, why is this not listed on the Check Permissions dialogue box? I know Read is the default for this group but almost everything on this site does not inherit permissions
Check permissions only checks the permissions of the current object that you invoked Check permissions on.
- If you do Check Permissions on the site, it will detail how a user has site level access only.
- If you do it on a document library, it will detail how the user has access to the document library only.
- If you do it on a file, it will detail how the user has permissions to the file.
If you need comprehensive permissions reporting on the site as a whole, you will need to write something to do that, or use third party tools to do so.
