4.105. mod_auth_kerb

Updated mod_auth_kerb packages that fix two bugs and add one enhancement are now available for Red Hat Enterprise Linux 5.
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 Fixes

BZ#456662
Prior to this update, the mod_auth_kerb source RPM could not be built by a non-root user. This was because the httpd-devel package places the apxs utility, which is needed to build the mod_auth_kerb package, into the /usr/sbin directory. This directory is not specified in the PATH variable for non-root users. With this update, the apxs utility is defined as being placed in the /usr/bin directory in the "mod_auth_kerb.spec" file, and the mod_auth_kerb SRPM can now be successfully built by non-root users.
BZ#734098
The "mod_auth_kerb" module did not use the Kerberos libraries in a thread-safe way. Therefore, if mod_auth_kerb ran under a multi-threaded Apache HTTP Server, authentication requests could terminate unexpectedly with a segmentation fault. With this update, the thread-safety problem has been fixed, and crashes no longer occur under these circumstances.
In addition, these updated mod_auth_kerb packages provide the following enhancement:
BZ#446670
The "KrbLocalUserMapping" Apache directive has been added to allow Kerberos principal names to be mapped to system user names.
Users are advised to upgrade to these updated mod_auth_kerb packages, which fix these bugs and add this enhancement.
