- If one is willing to look beyond Unix, this is more or less what is being
- done in the MS-DOS and Macintosh worlds when Kerberos is installed. In
- those environments, there exist no local user access controls, nor is it
- clear that any such controls would be effective.
-
- Kerberos can be integrated into the network software on such machines,
- moving, as you suggest, all authentication information to a centralized
- server. (I should say this is still a theoretical idea here because we
- haven't gotten our DOS Kerberos working yet.)
-
- NIS and similar systems are inappropriate for this sort of environment,
- which is, I think, why so many people are interested in any news about
- Kerberos or SPX for MS-DOS, MacOS, and Windows.

- I was recently attempting to figure out whether there was any use for
- ksu on MS-DOS. :-) I still haven't decided -- I need to figure out
- exactly what ksu does with TGTs before I decide whether we should port
- it.
