Description Kent Squires 2010-09-03 07:56:35 MDT

AIX 5300-12-01
32bit machine
any version of sudo 1.7.3 and up

if any one of the following are in /etc/sudoers, sudo hangs when executing a command (e.g. sudo df).  /var/log/sudo-io/seq is created, but that's it.

This happens on:
a custom compiled version
the BFF package
the RPM package


Defaults log_input
Defaults log_output
Defaults use_pty

This was fixed in trunk but didn't get merged to the 1.7 branch.  I've attached a fix.
