5.196. mod_auth_kerb

Updated mod_auth_kerb packages that fix a bug and add an enhancement are now available for Red Hat Enterprise Linux 6.
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.

Bug Fix

Due to a bug in the handling of memory lifetime when the module was configured to allow delegated credentials, the $KRB5CCNAME variable was lost after the first request of an authenticated connection, causing web applications which relied on the presence of delegated credentials to fail. The memory lifetime handling has been fixed, allowing such web applications to access delegated credentials.


Support for "S4U2Proxy" constrained delegation has been added, which allows mod_auth_kerb to obtain credentials on behalf of an authenticated user.
Users are advised to upgrade to these updated mod_auth_kerb packages, which fix this bug and add this enhancement.
