"Sorry, but you are not authorized to commit the specified command"
I get this error when I use_authentication=1 in the cgi.cfg and try to modify (for instance) a downtime on the webinterface.
The permissions of nagios/var/rw/nagios.cmd:
prw-rw---- 1 nagios nagioscmd 0 Apr 13 15:25 nagios.cmd
I have followed the instructions explicitly and tried EVERYTHING I can find or think of. Nothing solves this problem.
