   * Name: initgroups
   *
   * Description:
   *   The group database /etc/group is read to determine all groups of which
   *   user is a member.  The additional group group is also added to this set,
   *   which is then used to set the supplementary group IDs of the calling
   *   process.
   *
   * Input Parameters:
   *   user  - Name of the user to query the /etc/group database for.
   *   group - Additional gid to add to the list of group IDs.
   *
   * Returned Value:
   *   The initgroups() function returns zero if successful, and -1 in case of
   *   failure, in which case errno is set appropriately.
   *
