RHBA-2011:0907 - krb5 bug fix update

Synopsis

krb5 bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated krb5 packages that fixes a bug is now available for Red Hat Enterprise Linux 6.

Description

Kerberos is a network authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, a KDC (Key Distribution Center).

This update fixes the following bug:

• Certain versions of the KDC software (included for example in Red Hat Enterprise Linux 2.1 and 3) reject requests, which include KDC options the software does not recognize, and do not support the "canonicalize" option. When a client was configured to use one of these versions of the KDC software, the client failed to obtain credentials for authentication to other services. This interoperability regression was introduced in the update to Red Hat Enterprise Linux 6.1. With this update, an upstream patch has been provided to fix this bug. (BZ#714866)

Users of krb5 are advised to upgrade to these updated packages, which fix this bug.
