auto-import changelog data from pam-0.77-15.src.rpm Thu Oct 23 2003 Nalin Dahyabhai <nalin@redhat.com> 0.77-15 - don't install _pam_aconf.h -- apps don't use it, other PAM headers which are installed don't use it, and its contents may be different for arches on a multilib system - check for linkage problems in modules at %install-time (kill #107093 dead) - add buildprereq on flex (#101563) Wed Oct 22 2003 Nalin Dahyabhai <nalin@redhat.com> - make pam_pwdb.so link with libnsl again so that it loads (#107093) - remove now-bogus buildprereq on db4-devel (we use a bundled copy for pam_userdb to avoid symbol collisions with other db libraries in apps) Mon Oct 20 2003 Dan Walsh <dwalsh@redhat.com> 0.77-14.sel - Add Russell Coker patch to handle /dev/pty Fri Oct 17 2003 Dan Walsh <dwalsh@redhat.com> 0.77-13.sel - Turn on Selinux Fri Oct 17 2003 Dan Walsh <dwalsh@redhat.com> 0.77-12 - Fix pam_timestamp to work when 0 seconds have elapsed Mon Oct 06 2003 Dan Walsh <dwalsh@redhat.com> 0.77-11 - Turn off selinux Thu Sep 25 2003 Dan Walsh <dwalsh@redhat.com> 0.77-10.sel - Turn on Selinux and remove multiple choice of context.

Mon Jul 28 2003 Dan Walsh <dwalsh@redhat.com> 0.77-6 - Add manual context selection to pam_selinux Mon Jul 28 2003 Dan Walsh <dwalsh@redhat.com> 0.77-5 - Add pam_selinux Mon Jul 28 2003 Dan Walsh <dwalsh@redhat.com> 0.77-4 - Add SELinux support
