Full Discussion: [Solaris 10]NIS works only from "su"
Operating Systems Solaris [Solaris 10]NIS works only from "su" Post 302303065 by TonyFullerMalv on Wednesday 1st of April 2009 06:33:55 PM

If your "ypcat passwd does not include displaying the users' encrypted passwords then:

I'm rusty in this now but you need to copy your /etc/passwd, /etc/shadow and /etc/group files to a separate directory into which you have also copied the NIS Makefile and then run make to populate the NIS database with your users (from passwd) and their passwords (from shadow). If your users have NFS mounted home directories from a central NFS file server you may want to put the auto_home map file into NIS as well.

NIS is no longer in favour because someone may run:
Code:
$ ypcat passwd > textfile.txt

and the run cracker against the text file to determine the users passwords because NIS makes the users' encrypted password world readable.

I hope this gives you some helpful pointers...
