RHBA-2013:0860 - mod_auth_kerb bug fix update

Synopsis

mod_auth_kerb bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated mod_auth_kerb packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

The mod_auth_kerb package provides a module for the Apache HTTP Server designed to provide Kerberos authentication over HTTP. The module supports the Negotiate authentication method, which performs full Kerberos authentication based on ticket exchanges.

This update fixes the following bug:

  • Previously, when the KrbLocalUserMapping directive was enabled, mod_auth_kerb did not translate a principal name properly if the local name was of a higher length. Consequently, the Apache server returned the HTTP 500 error in such a scenario. A patch has been provided to address this issue and the module now correctly translates account names longer than their counterpart principal names. (BZ#867153)

Users of mod_auth_kerb are advised to upgrade to these updated packages, which fix this bug.

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 https://access.redhat.com/knowledge/articles/11258
