To manage the bischeck daemon from the bisconf web ui the following configuration needs to be added to the /etc/sudoers file:

Defaults:username !requiretty
nagios ALL= NOPASSWD: /etc/init.d/bischeckd restart
nagios ALL= NOPASSWD: /etc/init.d/bischeckd start
nagios ALL= NOPASSWD: /etc/init.d/bischeckd stop
nagios ALL= NOPASSWD: /etc/init.d/bischeckd pidstatus

Bisconf 0.1.0 must run on the same server as bischeck. Hopefully this may change in the future.
