Trying to set up a sudors file with password authentication on OES2 SP3
I'm a bit puzzled because of the PAM configuration. After some try and
error the following seems to work for an eDirectory user:

auth required
auth optional
auth optional

The default configuration does not include which does not
work. Also is set as required after OES install. My first
try was to include as optional without touching the other two
lines. But without setting to optional also sudo does not work.
The above configuration does look a bit strange to me. With all modules
set as optional will I risk that a user might authenticate so some
service including common-auth without supplying a correct password?
