 How to use NIS shadow map (Linux server, AIX clients)
        Hi,

        I have migrated master NIS server from AIX to Linux. That gives new
        NIS map, 'shadow'. But AIX NIS client does not seem to use this map,
        it uses 'passwd' map. Now I am forced to merge passwd and shadow
        during building NIS maps on the server. How do I make AIX NIS client
        use 'shadow' map to get encrypted passwords and other shadowed info ?

        Please give an advise. Thank you in advance.

You should teach AIX to undertand MD5 Hashes for passwords and a lot more,
but I don't think it's an easy job.

Have a look at Linux NIS help files : there should be an option which will
merge password and shadow file into a single map. The same for group and its
shadow file. Remember that Linux password usually are differently cripted so
AIX clients and Linux clients can NOT share the same users unless you revert
Linux to use crypt instead of his method.

If you *DO NOT* have clients using the currently available shadowed info via
NIS you can build your maps using the AIX data, keeping them separate from
linux ones. Maybe some problem will come when you need to change the passwords

        I already stumbled on that and now turned off MD5 passwords on my
        Linux.

        Yes, I found this option in /var/yp/Makefile and turned it on (as I
        wrote about that above).

        I think DES crypt is common to Linux and AIX. MD5 crypt may be Linux
        only, not present on AIX.

        I just appended AIX passwd and group maps to Linux /etc/passwd and
        /etc/group , then checked them for duplicates and converted by
        pwconv/grpconv. I often have to create new users with adduser, and
        making 'adduser' to add them to files different from /etc/passwd and
        /etc/group is too complicated to me. At least I did not try to find
        the way.
