- this is a local implementation of a privileges backend, with
- privileges stored in a tdb. Most passdb implementations will
- probably use this backend, although some (such as pdb_ldap) will
- store the privileges in another manner.
-
- The basic principle is that the backend should store a list of SIDs
- associated with each right, where a right is a string name such as
- 'SeTakeOwnershipPrivilege'. The SIDs can be of any type, and do not
- need to belong to the local domain.
-
- The way this is used is that certain places in the code which
- require access control will ask the privileges backend 'does this
- user have the following privilege'. The 'user' will be a NT_TOKEN,
- which is essentially just a list of SIDs. If any of those SIDs are
- listed in the list of SIDs for that privilege then the answer will
- be 'yes'. That will usually mean that the user gets unconditional
- access to that functionality, regradless of any ACLs. In this way
- privileges act in a similar fashion to unix setuid bits.
