Objects and Paths
~~~~~~~~~~~~~~~~~
Access permissions are assigned to objects, such as a datastore, a namespace or
some system resources.
We use file system like paths to address these objects. These paths form a
natural tree, and permissions of higher levels (shorter paths) can optionally
be propagated down within this hierarchy.
Paths can be templated, that means they can refer to the actual id of an
configuration entry. When an API call requires permissions on a templated
path, the path may contain references to parameters of the API call. These
references are specified in curly braces.
Some examples are:
* `/datastore`: Access to *all* datastores on a Proxmox Backup server
* `/datastore/{store}`: Access to a specific datastore on a Proxmox Backup
server
* `/remote`: Access to all remote entries
* `/system/network`: Access to configuring the host network
* `/tape/`: Access to tape devices, pools and jobs
* `/access/users`: User administration
* `/access/openid/{id}`: Administrative access to a specific OpenID Connect realm
Inheritance
^^^^^^^^^^^
As mentioned earlier, object paths form a file system like tree, and
permissions can be inherited by objects down that tree through the propagate
flag, which is set by default. We use the following inheritance rules:
* Permissions for API tokens are always clamped to the one of the user.
* Permissions on deeper, more specific levels replace those inherited from an
upper level.
