// Auth Group (Process and Thread) Processing
//
// afsredir.sys implements a set of generic Authentication Group
// operations that can be executed by processes.  The model supports
// one or more authentication groups per process.  A process may switch
// the active AuthGroup for any thread to any other AuthGroup the process
// is a member of.  However, processes cannot assign itself to an
// AuthGroup that it is not presently a member of.  A process can reset
// its AuthGroup to the SID-AuthGroup or can create a new AuthGroup that
// has not previously been used.
//
//  IOCTL_AFS_AUTHGROUP_CREATE_AND_SET
//      Creates a new AuthGroup and either activates it for
//      the process or the current thread.  If set as the
//      new process AuthGroup, the prior AuthGroup list is
//      cleared.
//
//  IOCTL_AFS_AUTHGROUP_QUERY
//      Returns a list of the AuthGroup GUIDS associated
//      with the current process, the current process GUID,
//      and the current thread GUID.
//
//  IOCTL_AFS_AUTHGROUP_SET
//      Permits the current AuthGroup for the process or
//      thread to be set to the specified GUID.  The GUID
//      must be in the list of current values for the process.
//
//  IOCTL_AFS_AUTHGROUP_RESET
//      Resets the current AuthGroup for the process or
//      thread to the SID-AuthGroup
//
//  IOCTL_AFS_AUTHGROUP_SID_CREATE
//      Given a SID as input, assigns a new AuthGroup GUID.
//      (May only be executed by LOCAL_SYSTEM or the active SID)
//
//  IOCTL_AFS_AUTHGROUP_SID_QUERY
//      Given a SID as input, returns the associated AuthGroup GUID.
//
//  IOCTL_AFS_AUTHGROUP_LOGON_CREATE
//      Given a logon Session as input, assigns a new AuthGroup GUID.
//      (May only be executed by LOCAL_SYSTEM.)
//
// New processes inherit only the active AuthGroup at the time of process
// creation.  Either that of the active thread (if set) or the process.
// All of the other AuthGroups associated with a parent process are
// off-limits.
