If you're referring to the 'type' of encrypted password I think, then
the encrypted text is a 2 char salt, + 2-11 char strings, for a 
total length of 23 yes?

If so, strip the password to just the first 13 characters and NetBSD
should be happy. The ones I've seen simply encrypt the first 8 characters
into the first 11 crypted, and the 2nd 8 into the 2nd 11 crypted.
