Hi, today we were hit by a bug in nscd. After the update to glibc-2.5-81.el5_8.4 nscd did not work with selinux in enforcing mode. getent passwd loginname return an empty result, also login for user did not work. workarounds are: a) stop nscd b) switch selinux into permissive mode stop nscd delete nscd cache files start nscd again This is reported as Bug #841752 https://bugzilla.redhat.com/show_bug.cgi?id=841752 Sincerly, Klaus -- Rechnerbetriebsgruppe / IT, Fakultät für Physik Klaus Steinberger FAX: +49 89 28914280 Tel: +49 89 28914287
