Use WinNT User Accounts on Linux -- Centralize User Accounts

Post by Ross X » Wed, 13 Sep 2000 04:32:46



Dear there,
All my user accounts are on my Windows NT 4.0 server. But my ftp and email
servers are Linux. Is it possible to use the WinNT accounts onto my Linux
servers so that each user only has one username/password on my network? How
can I configure it if possible?
Any help would be appreciated.
Ross

The way I know is vice versa. Linux holds all the account-information and
with a samba its shared as win-NT-domain-information. So every user has
the same passwd for nt-logon/email/ftp ...

There is also a authentication-method that allows you to verify a passwd
against a smb-source (samba or nt-server, workstation). If you manage to
include this in your email, ftp-software you have won. I dont know if
there are pam-modules for that, I just know it from perl.

Maybe this helps,

Assuming you're using a version of Linux that support PAM, there is a
PAM/NTDOM module, which allows you authenticate Linux users from an NT
server.  Look on www.samba.org for information about the samba-ntdom
mailing list, they may be able to provide more information.

1. Centralized user accounts

We have a small cluster of Solaris 2.6, 7, and soon 8 boxes (plus some AIX
and Linux). We are at the point where just maintaining users per box is
becoming a major pain. Some options come to mind:

1) NIS/NIS+. This seems to be the "old way" of doing things.

2) We have a CiscoSecure server here, bringing up the option of RADIUS (or
TACACS). Having used RADIUS before, this just doesn't seem to really fit. On
the other hand, if I am not mistaken, CiscoSecure uses Netscape Directory
Server 3 as a back-end.

3) LDAP. This is where things are heading (can you say Active Directory and
Novel Directory Server?). However, I'd prefer to be using Netscape/iPlanet
Directory Server over Sun DS 3.1. It also seems like NIS+ is still used on
the client computers?

Some other questions:

A) Which of the above would I need to keep a /etc/passwd file with all the
users in it (e.g. so 'ls' shows usernames).

B) Ay recommendations for pushing out /etc/passwd and other things?
Cfengine looks promising.

C) What about fault tolerance/redundancy for the user server?

D) What about authorization information? Can I store in the central user
server what computers someone is allowed to login on and which ones they can
only so the suid thing?

Thanks!
