Description Dale R. Worley 2007-03-28 12:33:25 MDT

When "Defaults requiretty" is present in /etc/sudoers, sudo refuses to run if the process does not have a tty even if sudo will not prompt the user for a password.  This can be problematic in various circumstances, so the user removes "requiretty" from /etc/sudoers.  But that negates the additional security that "requiretty" provides.

The option behaves as intended.  Part of the reason for requiretty is to prevent users without a real login session from running sudo.  For example, cgi scripts.
