I have done several informal surveys at various HP-UX classes.

Older legacy shops do use NIS and NIS+ but NIS+ is very complex and hard to administer. I've found less than 10% in my survey use NIS+. 25% used NIS.

The trend in the industry seems to be to go with an LDAP server, either Linux or Windows and handle normal user authentiation there.

I agree with Steven.

I've supported ONC products (i.e. NFS/NIS/NIS+/AutoFS/CacheFS/etc.) at HP for over 10 years so I got to hear all the marketing hype of how NIS+ was going to replace NIS with its rich feature set and expandability.

The reality from my perspective is that very few customers ever successfully implemented NIS+ in their environments and the majority of customers who tried to roll out NIS+ ended up giving up and switching back to NIS.

The concensus opinion of my customers was that NIS+ was simply to complicated and frustrating to administer. The number of commands and their various options were too many for most customers to ever take the time to get familiar with and they eventually gave up.

Sun has announced end of support for NIS+ and HP has done the same. We will continue supporting NIS+ on those HP-UX releases that ship with NIS+, but my understanding is that the next major release of HP-UX will not offer support for NIS+, so customers would be wise to investigate alternatives like LDAP.

I can only remember 1 shop where NIS or NIS+ was used. NIS had lots of security worries and NIS+ is another bear in itself.

NIS usage is rapidly declining mainly because the passwd hash is readily available to anyone in the domain; it's replacement NIS+ gets around that issue but is rapidly falling out of favor and is not expected to be widely supported in the future. Neither of these options really supply the security level demanded by most systems now. Your best bet is LDAP but you do not have to rely upon mamby-pamby windows boxes for authenication; Netscape Directory Server runs just fine on HP-UX and can house your LDAP data.
