- We use YP with the (roughly) current os versions on DEC 5000's, Iris4D's,
- and NeXT's, and with outdated os on Sun 3-?0's and Iris beasts of various
- vintages. We have had a tolerable but hardly great experience with yp.
- It does work, and hasn't caused any major disasters. On the other hand
- it often feels that any os-update now we're going to have to rethink
- everything :)
-
- Different vendors sometimes produce incompatible nis versions, as when
- the Sparc SLC was released and couldn't talk to SGI's. Different vendors
- allow differing abilities to fine-tune what files are exported and the order
- in which file/map is accessed -- DEC provides nice features in this dep't,
- which mostly work, while SGI is awful -- once you turn on yp, the machine
- will only look at the maps (for other than the group and passwd files), so
- you have to yp export things like /etc/services which is tricky to make
- complete enough so that it's a superset for EVERY machine on the network.
-
- There are the semi-well-known security problems with yp, which
- I don't understand at all :) and the fact that yp servers tend to go
- out of their minds every so often and start talking to other domains.
- It has happened to us -- weird. Where DID all those passwd changes go?
- Noone knows... :)
-
- We're trying to find some way out of yp. We're looking at acmaint with
- some lack of enthusiasm, Moira (from Athena) with even MORE trepidation
- (it's just too big for us, plus requires a proprietary db package), and
- a few others, none of which look particularly simple to make work in our
- environment. Maybe it's a hard problem :)
