The password formats should be the same on any version of FreeBSD
whatsoever, assuming they are supported at all.  However, FreeBSD does
not keep passwords in plain text on any version, so I'm not really
clear on what you were doing in the first place.

What you want to do should definitely be possible.  [It doesn't sound
like a great security idea, for roughly the same reasons that NIS
isn't appropriate for hostile environments, but that's another issue.]
