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:

/etc/pam.d/common-auth:
#
auth required pam_env.so
auth optional pam_nam.so
auth optional pam_unix2.so
#

The default configuration does not include pam_nam.so which does not
work. Also pam_unix2.so is set as required after OES install. My first
try was to include pam_nam.so as optional without touching the other two
lines. But without setting pam_unix2.so 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?
