Newbie Alert: I have a Redhet 7.3 machine working correctly. I
started playing with a Redhat 8.0 machine. Is there anyway to sync
the users and passwords to the new machine? I guess I just don't know
what I'm looking for. Pointing to a how-to-doc would be great.

Thanks

Copy the user entries from /etc/shadow and /etc/passwd on the old box into
the same files on the new box. Remember to back up these files first.

Merge the files /etc/passwd and /etc/group.
If you have shadow-file enabled, I'm not sure where the shadow file
is, perhaps /etc/shadow. (I don't have it enabled.)

In the old days I used to maintain a NIS database for the passwords,
but I don't know if there is something more modern today. Pam modules
that access ldap dtabases, I guess. Or Kerberos servers. I am quite
sure that NIS can be made to work on a linux platform, though.

Having a NIS database meant all computers in the company network
recognized the same users and passwords. You could still have problems
logging into a new machine, if there was no /home/myname directory on
the new computer. After I quit that job, there came something called
NIS+, and later still, automounter, which allowed various ways of
making that problem go away, but as said, I no longer work in a strong
Unix environment and I no longer do systems administration, so I
cannot help you any further.
