SOLVED: nmcli under cron

[logical american <website reader3 gmail com>]

This morning I tried executing the nmcli command under root cron and it 
worked as desired.  This told me what I needed to know, that the user 
cron did not allow the sudo nmcli command to work or have sufficient 
privileges.

I made a copy of the nmcli executable in the /usr/local/bin folder and 
changed the owner and group to match that of the user's crontab 
permissions, then edited the sudoer's file to add only and specifically 
that command to NOPASSWD permissions.

nmcli now works as expected under the user's crontab job.

I consider this problem fixed.
