I'm not sure what you're running into; I don't think either of these could
have been the problem.  Perhaps you were running into the fact that the
2.3.0 ckpasswd program was pretty picky about file format?  2.3.1 is a bit
more relaxed in that department.

iter is set above to colon + 1, at least in STABLE.

STABLE already had that change, but I've also now made nnrpd
