[mythtv-users] What can cause Authentication Rejected Error When Running MythShutdown?

[nospam312]

Should have made clear that it is already in the sudoers.  If I run
with logging (-v all) the error is output before any log messages.

I also get the problem with running mythbackend also?  (perhaps others)

MythTV still appears to be working however?

Any suggestions?

TIA
