Shadow passwords aren't a function of the kernel in linux. They are a
user mode function. In the more recent linux distributions, shadow
passwords and/or portable authentication modules (PAM) can be used.
Interestingly enough, there are PAM modules that allow a linux box to use
another RADIUS server for authentication for telnets, ftp, etc.
Biggest problems you may face when using system passwords may be the fact
that BSD, I believe uses a different crypt setup that is essentially
incompatible with the crypt in Linux. So encrypted passwords cannot
be simply transferred from one to the other.

None, or any of them. Depends on what you need for integration. You
certainly benefit if you stay with one OS.
