pmjoin_plugin fails on AIX

"ERROR: Architecture mismatch, /bin/sudo is other, plugin is 64-bit XCOFF executable, did you install the wrong plugin package?"

Try setting the /usr/bin path with the join command, example:

PATH=/usr/bin:$PATH; /opt/quest/sbin/pmjoin_plugin -a server

Note: please check that the path you specify contains the actual sudo binary and not a symbolic link. AIX often links /usr/bin/sudo to /opt/freeware/bin/sudo, in which case you will need to set your PATH to use /opt/freeware/bin instead of /usr/bin.
