-N we can probably work around (only used for groupmap).  -S is harder,
perhaps removing that from the popt_common.c side would be best (and
fix source4/lib/cmdline/popt_credentials.c to match). 

I'm hesitant about breaking scripts but making this use the common
credentials parsing code is really important (not just for parsing the
file, but for the rest of the things it gives us).

If you could give using the POPT_COMMON_CREDENTIALS one more try I
would appreciate it.  There is a lot we gain if we unify this.
