[ale] How to get Apache 2.2 to authenticate via PAM

[seca900rider at gmail.com (Raylynn Knight)]

I am in the process of migrating an Apache 2.0 hosted svn server
(version 1.3.1) on SLES 9.2 to a new Centos 6.2 host.  I'm having a
problem finding the correct replacement for AuthPAM authentication
currently used.  Apparently the mod_auth_pam module is considered
obsolete and various web searches haven't been very helpful in
suggesting a replacement.  What is the current best practice method
for authenticating Apache via PAM?

Thanks,
