A UserPrincipal representing a group identity, used to
determine access rights to objects in a file system. |
|
A Principal representing an identity used to determine access rights
to objects in a file system.
On many platforms and file systems an entity requires appropriate access
rights or permissions in order to access objects in a file system. The
access rights are generally performed by checking the identity of the entity.
For example, on implementations that use Access Control Lists (ACLs) to
enforce privilege separation then a file in the file system may have an
associated ACL that determines the access rights of identities specified in
the ACL.
A UserPrincipal object is an abstract representation of an
identity. It has a name that is typically the username or
account name that it represents. User principal objects may be obtained using
a UserPrincipalLookupService, or returned by FileAttributeView implementations that provide access to identity related
attributes. For example, the AclFileAttributeView and PosixFileAttributeView provide access to a file's owner.
