I worked out how to set up debug for sudo. sudoers_debug is deprecated now, but I created /etc/sssd.conf with a line Debug sudo /var/log/sudo_debug all@debug and I saw this in the debug output: Dec 10 15:42:57 sudo -> sudo_sss_check_host @ ./sssd.c:557 Dec 10 15:42:57 sudo val=+cog Dec 10 15:42:57 sudo -> addr_matches @ ./match_addr.c:189 Dec 10 15:42:57 sudo -> addr_matches_if @ ./match_addr.c:61 Dec 10 15:42:57 sudo <- addr_matches_if @ ./match_addr.c:99 := false Dec 10 15:42:57 sudo <- addr_matches @ ./match_addr.c:199 := false Dec 10 15:42:57 sudo -> netgr_matches @ ./match.c:899 Dec 10 15:42:57 sudo <- netgr_matches @ ./match.c:918 := false Dec 10 15:42:57 sudo -> hostname_matches @ ./match.c:758 Dec 10 15:42:57 sudo <- hostname_matches @ ./match.c:769 := false Dec 10 15:42:57 sudo sssd/ldap sudoHost '+cog' ... not The problem is that the hostname command on the client was returning a short hostname, ipaclient21, instead of a FQDN, ipaclient21.testdomain21.com and when I forced the hostname to be the FQDN the sudo command worked. The short hostname comes from the fact that the client machine is an openstack instance, and that appears to be a feature of openstack instances :( Chris -- Manage your subscription for the Freeipa-users mailing list: https://www.redhat.com/mailman/listinfo/freeipa-users Go To http://freeipa.org for more info on the project
