[drbd-mc] Using sudo.

[Caspar Smit]

Hi Rasto,

I created a user "john" which has sudo access.

When I add a host and type john as username and select "use sudo" i
immediatly get the following error:

Failed.
Command failed.1

And in the console is see:

[john at 192.168.0.12:~#] /usr/local/bin/drbd-gui-helper-0.8.12 all
DRBD MC sudo pwd:
[john at 192.168.0.12:~#]

Shouldn't there be a "sudo" command before /usr/local/etc.....

Because when I type the command in an ssh shell it works (but only with the
sudo command):

$ sudo /usr/local/bin/drbd-gui-helper-0.8.12 all
