Password Synchronization from UNIX Does Not Work When You Use Yppasswd Command (316055)


The information in this article applies to:

  • Microsoft Windows Services for UNIX 3.0
This article was previously published under Q316055

SYMPTOMS

When a UNIX user tries to change their password on a UNIX platform that is configured to use the UNIX NIS component for password validation, the user cannot do so. This occurs when the user uses the yppasswd command. Under these conditions, the password is not replicated to the Windows computer by using the Windows Services for UNIX 3.0 password synchronization component.

CAUSE

If the Windows Services for UNIX Password Authentication Module (PAM) is installed on a UNIX NIS Master, the yppasswd command does not use the pam_sso infrastructure.

RESOLUTION

To make password synchronization work in an NIS/NIS+ environment:
  1. Link yppasswd to the passwd command.
  2. On all the NIS UNIX clients (whether the "NIS Master" is a Windows Services for UNIX NIS Server or a UNIX NIS server), edit the Etc/Nsswitch.conf file and set it to use NIS / NIS+.
  3. If the "user" is not present in the local /etc/password | shadow files, the passwd|yppasswd command that was run on the UNIX client (NIS client) computer changes the NIS password for the user on the NIS master database.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
