RHBA-2012:0246 - Bug Fix Advisory

Topic

An updated pam_krb5 package that fixes a bug is now available for Red Hat
Enterprise Linux 5.

Description

The pam_krb5 package allows PAM-aware applications to check user passwords with
the help of a Kerberos KDC.

This updated pam_krb5 package fixes the following bug:

• Previously, if a system was configured to perform Kerberos authentication

using PKINIT, users who attempted to change their passwords using the "passwd"
command or other PAM-aware application, while a smart card was inserted, would
be erroneously prompted for the smart card PIN. With this update, the plugin
returns an error to any requests for non-password information while attempting
to obtain password-changing credentials. As a result, the unnecessary request
for the smart card PIN is no longer made to the user in the scenario described.
(BZ#715073)

All users of pam_krb5 are advised to upgrade to this updated package, which
fixes this bug.
