[sudo-users] SUSE 11, sudo 1.8.1p2, extra output

[Jeff Earickson]

All,


A new SUSE 11 box (2.6.32.36-0.5-default #1 SMP 2011-04-14 10:12:31
+0200 x86_64 x86_64 x86_64 GNU/Linux), with sudo 1.8.1p2 installed via
tarball (not the rpm that comes with SUSE 11).  My problem:  when
anyone sudo's to root, they get extra output about who has logged in
or out recently:

i: sudo -s

I have never seen this behavior on any other system (Solaris, HPUX,
Redhat).  How to make it go away?  I searched around in the
sudoers.conf file, and also thought that maybe it came via syslog
output (syslog-ng, nope).  Help...
