pmjoin_plugin error -- /etc/sudo configured successfully but sudo plugin non-operational

The issue occurs when joining the Privilege Manager for Sudo plug-in host to a policy server, and the pmjoin_plugin command returns the following error message.

*** Verifying plugin status [FAIL]
       - ERROR: /etc/sudo.conf configured successfully but sudo plugin non-operational

The issue was reported using sudo binaries downloaded from the HP-UX porting & archiving centre (hpux.connect.org.uk), but might also occur if sudo binaries packages are downloaded from repositories other than the main sudo site (www.sudo.ws).  In this instance, the porting site changed the location of the sudo.conf path to /usr/local/etc/sudo.conf in the source code, instead of using the "--sysconfdir=/usr/local/etc" configure option.  The pmjoin_plugin script uses the "Configure options" section reported by sudo -V to determine the expected location of the sudo.conf file.

Resolution # 1
The packages can also be downloaded from sudo.ws website and are known to work.

Workaround # 1
You could also symlink /etc/sudo.conf to /usr/local/etc/sudo.conf (or wherever it's expected to be) as a workaround. Copy will not work as we remove the entry in /etc/sudo.conf if the join fails.

Creating the symlink (ln -s /etc/sudo.conf /usr/local/etc/sudo.conf) prior to running pmjoin_plugin should do the trick.
