It appeared between 1.8.10 and 1.8.15. ** Bug watch added: bugzilla.sudo.ws/ #757 http://bugzilla.sudo.ws/show_bug.cgi?id=757 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to sudo in Ubuntu. https://bugs.launchpad.net/bugs/1591137 Title: sudo ignores shortname aliases in sudoers file Status in sudo package in Ubuntu: Confirmed Bug description: Our sudoers file contains host aliases which all work fine on versions of Ubuntu < 16.04. On 16.04, it has become necessary to include the FQDN of the machine in order for sudo permissions to be granted. I have reproduced this problem on two cleanly-installed servers. i.e. This entry in /etc/sudoers does not work for members of sudo group:- %sudo ourserver This entry in /etc/sudoers does work for members of sudo group:- %sudo ourserver.our.domain Extra information which may be of interest: 'hostname' returns the shortname on both Ub1604 and Ub1404 installations /etc/hosts lists machines by fqdn and then shortname on both platforms, i.e. ip.ad.dr.es ourserver.our.domain ourserver /etc/resolv.conf is set to search our.domain, same on both platforms sudo package version is 1.8.16-0ubuntu1.1 Bw John To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/1591137/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
