Hi Group,

I run the Linux server component of a computer science lab in Iowa. We
use NIS to do our user auth for all of the Linux lab machines and just
recently the server stopped updating the NIS maps with new users. We
run a useradd on the NIS master, set the password, then run "make -C
/var/yp". In November this system worked, but as of this past weekend,
the lab machines aren't seeing the new users.

Do you guys have any tips for troubleshooting this?

Thanks!
Ian

I solved this issue by re-issuing the ypinit command. I think the DNS
name for the server was incorrectly entered.

If you can, I'd actually upgrade to LDAP with Samba integration. It works
quite well.

Right. We were looking at that but I haven't found a decent HOWTO on
moving previously-created NIS accounts over to LDAP while preserving
account names, UIDs and passwords accross Samba and Unix login.

There are some useful migration tools in the openldap RPM's and the openldap
source tarballs. Check them out, in /usr/share/openldap/migration under
RedHat systems.
