8.142. mod_auth_kerb

Updated mod_auth_kerb packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The mod_auth_kerb packages provide 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.

Bug Fixes

This update adds the missing description of the "KrbLocalUserMapping" option to the README file.
Previously, the mod_auth_kerb module was not compatible with the way certain browsers, such as Mozilla Firefox, handled an expired Kerberos ticket. As a consequence, opening a Kerberos-protected page in these browsers with an expired Kerberos ticket caused mod_auth_kerb to fail. With this update, the error in mod_auth_kerb has been addressed and the mentioned problem no longer occurs.
Due to a bug in the underlying source code, when the "S4U2Proxy" extension was configured, the mod_auth_kerb module did not renew tickets that were not valid yet. This update applies a patch to fix this bug and the tickets are now correctly renewed as expected.
Users of mod_auth_kerb are advised to upgrade to these updated packages, which fix these bugs.
