excellent (luke, trying to be encouraging).

1) *unfortunately* i've _just_ modified this _exact_ area of code in the
last day or so, and your patch clashes with in in cvs main.

2) your new format for private/smbpasswd is incompatible with the old
format.  can you arrange so that the length is left at 14 characters? some
of those bits are mutually exclusive (fortunately) - ACB_NORMAL, WSTRUST,
SVRTRUST and DOMTRUST.  hopefully jeremy didn't realise this so we have
some spare room in there :-)

if you _have_ to make it 15 chars then pls make sure you can read old
format (14 chars) as _well_ as new format.  remember, mod_smbfilepwd_entry
can only modify in-place.

3) is the new bit you're adding a standard NT one?
