In DSEE, only the root user is exempt from access control evaluation.
While administrators can create access control instructions (ACIs) that give normal users full access to any content, they can also create ACIs that would make a portion of the data inaccessible to those users. Additionally, some tasks can only be accomplished by the root user and the capabilities assigned to the root user can't be restricted.
The Server uses a privilege subsystem to control the capabilities available to various users. Non-root users can be granted limited access to certain administrative capabilities, and restrictions can be enforced on root users. Additionally, certain risky actions require that the requester have certain privileges in addition to the sufficient access control rights to process the operation.
These risky actions include:
- Interacting with the server configuration
- Changing another user’s password
- Impersonating another user
- Shutting down and restarting the server
