RHEA-2012:0204 - yp-tools enhancement update

Synopsis

yp-tools enhancement update

Type/Severity

Product Enhancement Advisory (none)

Topic

An updated yp-tools package that adds one enhancement is now available for Red Hat Enterprise Linux 5.

Description

The Network Information Service (NIS), formerly known as Sun Yellow Pages (YP), is a system that provides network information (login names, passwords, home directories, group information) to all machines on a network. NIS can enable users to log in on any machine on the network as long as the machine has the NIS client programs running and the user's password is recorded in the NIS passwd database.

This update adds the following enhancement:

  • When using the /etc/passwd.adjunct configuration file, the previous version of the ypasswd client program did not recognize the salt used for hashing a new password and chose the Data Encryption Standard (DES) as the default hash function. This update introduces a new "YP_PASSWD_HASH" environment variable, which allows users to explicitly specify either "md5" (for the MD5 Message-Digest Algorithm) or "des" (DES) as the hash algorithm. (BZ#682037)

All users of yp-tools are advised to upgrade to this updated package, which adds this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
