Dial-up password protection schemes for Sun?

[ncrcis!cape at ncrnd3.stpaul.ncr.com]

I'm looking for a way to implement a secondary password on dial-up
connections to Suns.  System V Unix has it and we'd like to have it or a
functional equivalent on our Suns.  Any leads would be most welcome.

Thanks,
