Abstract

This discloses a flexible mechanism to determine rights granted to processes requesting access to resources. The mechanism is implemented in the Distributed Computing Environment (DCE) for OS/2* Distributed File System (DFS) Client. Each requesting process is granted specific access rights according to a login context which it holds, or a default context which is assigned to it. Default contexts are specified by various methods.

Flexible Specification of Distributed Computing Environment Security
Login Contexts

      This discloses a flexible mechanism to determine rights granted
to processes requesting access to resources.  The mechanism is
implemented in the Distributed Computing Environment (DCE) for OS/2*
Distributed File System (DFS) Client.  Each requesting process is
granted specific access rights according to a login context which it
holds, or a default context which is assigned to it.  Default
contexts are specified by various methods.

      The DCE for OS/2 DFS Client provides for flexible specification
of DCE Security Login Contexts.

      When DFS file I/O is requested from an OS/2 process, access
rights are granted according to one of the following (in order of
precedence):
  1.  The DCE security context currently defined for that session, if
       any.
  2.  The current system-wide DCE security context for the OS/2 host,
       if any.
  3.  The DCE security context under which the main DFS daemon (dfsd)
       was started, if any.
  4.  The OS/2 DCE Host's machine context, "hosts/<hostname>/self".

      Each file access request handled by the OS/2 DFS Client is
granted rights to DFS files according to the login context held by
the requesting process.  A process obtains a DCE Security Login
Context through the "dcelogin" command or through the "sec_login"
programming interface.

      The DFS Client also provides file access to pro...
