SUMMARY: NIS+ and other flavors of UNIX: Compatible?

My appologies for not sending this out sooner. The awesome list deserves
more respect than that. I hope any SysAdmin will understand the feeling
of being inundated with work.

My question is stated below as the first attachment. It basically asked
if IBM's AIX, HP's HP-UX and DEC's DEC UNIX operating systems were
compatible with NIS+ from Sun's Solaris. Many thanks to the people who
answered.

The basic answer is no unless NIS compatibility mode is turned on because
those other OS's only support NIS. But then the maps don't update both
ways - passwd changes would always have to be done on a NIS+ client or the
NIS+ server and NOT the plain NIS client.

If the OS is HP-UX version 11 or IBM AIX 4.3 and they have ONC+ installed
then a NIS+ SUN master might work. I couldn't find anything from DEC
UNIX about ONC+. I also couldn't find any information on AIX's support
for ONC+. Oh well.

Subject: NIS+ and other flavors of UNIX: Compatible?

I was wondering if anyone out there has experience enough to tell me if the
NIS+ service from Solaris 7 is compatible with NIS clients on other flavors
of UNIX?
I have a network with the Sun boxes acting as all critical servers (of
course ;) ) and many systems running HP-UX 10.x, AIX 4.3.x, and DEC UNIX
4.0X.
I'd like to make use of the features of NIS+ in Solaris 7 - namely password
aging and tighter control on passwords - then again, anything is better
than NIS on SunOS 4.1.4!!! But I am concerned that other flavors don't
play with NIS+ but only straight NIS.
I will summarize... and support this awesome resource! Job well done to
all those kind souls who contribute! (Enough buttering? just kidding :)
)
Thanks in advance,
-Steve

Other systems which use ONC+ (which *may* mean they use NIS+) are
limited to:
     HP-UX 11
     AIX 4.3
     Sequent's OS (Dynix???)
I just got this info from Sun a couple weeks ago.

NIS+ master do have NIS compatible mode for connecting NIS clients

Hi Steve,
A partial answer - I believe that Digital Unix 4.0D is NIS+
compatible.
Regards,
Nick.

Nisplus only plays with nisplus. Although being quite robust no other vendors adopted the standard and thus it is solely contained on the SUN. Again, nisplus will not talk to nis. -- Ray ################################################################# # Raymond P.

Good evening, Steve. Yes, it's possible to merge NIS+ with NIS. You simply mus setup your NIS+ Server (Master and Replica[s]) in NIS Compatibility Mode. (Option -Y of rpc.nisd), uncomment line 'EMULYP="-Y"' in/etc/init.d/rpc. But I believe you cannot change passwords from your NIS clients - you must find a possibility that your users can this from a NIS+ machine. Wishing you success, Guenter

You would have to run the NIS+ server in NIS compatibility mode, which would mean security is better than straight NIS, but not as good as NIS+. Among other things, the encrypted passwords become available for everyone like in NIS. Password aging would also be a problem, I guess. You may have to either rely on people having to log in to the Sun's, and thereby being forced to change passwords or make up something in the login sequence that logs in on a Sun and does some simple magic. You should also consider the LDAP server that comes on the Easy Server CD (or whatever it's called) in Solaris 7. The Solaris license includes a license for a certain amount of entries. So you may have to add additional licenses. This LDAP server can run in NIS and Radius compatibility modes. This means you can have one repository for clients supporting LDAP that also works with legacy systems supporting NIS and/or radius (typically dial-in routers). Sun is moving towards LDAP, so I wouldn't invest in NIS+ now. Most other Unix vendors will also move to LDAP. And if you are lucky, Microsoft may also be able to work with a standard LDAP server, although I kind of expect them to demand a MS LDAP server (I guess that will 'enhance' the protocol so that they force everyone running NT desktops to have an NT LDAP server as well if they can get away with it). Sun are currently doing a lot of work on NT integration. With the new products You should be able to use the Sun as Primary Domain Controller on your network as well.
