   5     Return failure in getnetgrent only when all netgroups have been searched (#17363)
   6
   7     The netgroups lookup code fails when one of the groups in the search
   8     tree is empty.  In such a case it only returns the leaves of the tree
   9     after the blank netgroup.  This is because the line parser returns a
  10     NOTFOUND status when the netgroup exists but is empty.  The
  11     __getnetgrent_internal implementation needs to be fixed to try
  12     remaining groups if the current group is entry.  This patch implements
  13     this fix.  Tested on x86_64.

  15         [BZ #17363]
  16         * inet/getnetgrent_r.c (__internal_getnetgrent_r): Try next
  17         group if the current group is empty.
