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. -*/ - -/* - The terms 'right' and 'privilege' are used interchangably in this - file.
