SUMMARY: NIS, PAM and an old question

Hi all!

My question was:

 We have in the past some discussions about a solution to allow only
 root login in a server, while running NIS.

 The only solution was every time, to disable NIS for passwd in
 /etc/nsswitch.conf (something like this: passwd: files ).

 This has some disadvantages (we can only see the UIDs, problems
 with samba and so on ...).

 Well, now i get a hint, that Solaris 2.5.1 is delivered with PAM.
 (I know, Solaris 2.6 has also PAM and it has some docs).

 Solaris 2.5.1 has no docs for PAM, i think.

 My question now is:

 Is there any PAM configuration for Solaris 2.5.1 to allow only root login
 to the host while running NIS?

 Which PAM module uses only /etc/passwd for authentification?

Well, old question - old solution:

 I change passwd in nsswitch.conf to:

   passwd: compat

 And i add a line to /etc/passwd:


 Running pwconv and it works now.

I get no hints for a PAM solution.

I don't know my mistake in former times. I tried it nearly in the
same way ... :-} . But i think, it is very important to use only the
passwd-line for NIS. For NIS+ is a second line passwd_compat necessary.
