RHEA-2011:1561 - yp-tools enhancement update

Synopsis

yp-tools enhancement update

Type/Severity

Product Enhancement Advisory (none)

Topic

An enhanced yp-tools package that provides an enhancement is now available for Red Hat Enterprise Linux 6.

Description

The Network Information Service (NIS) is a system which provides network information (login names, passwords, home directories, group information) to all of the machines on a network. NIS can enable users to login 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. NIS was formerly known as Sun Yellow Pages (YP).

This updated yp-tools package adds the following enhancement:

  • When using the passwd.adjunct file, the ypasswd client program did not recognize the salt used for hashing a new password and therefore chose DES as the default hash function. A new environment variable YP_PASSWD_HASH, which allows users to choose the hash algorithm, was added. (BZ#699666)

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

Solution

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

This update is available via 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
