From d1d5508011bfbd594f4d1c61d20b0ab9fb1bdc1d Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 22 Nov 2010 11:11:24 -0500 Subject: Fix multiple nss_compat initgroups() bugs Compat initgroups() is completely broken; the code will always set skip_initgroups_dyn to true, so initgroups() will never be actually called, but due to the nature of the code, setgrent() won't be called either - thus, subsequent invocations of initgroups() will not return the NIS group list anymore. This is a simple patch that makes sure skip_initgroups_dyn is set only in case initgroups is not available; it also attempts to handle the unavailability of other NSS interfaces better.
