AuthDigestFile No Longer Available In Apache 2.2

I'm working on a migration from CentOS 4 (Apache 2.0) to Ubuntu 8.04 (Apache 2.2).

I restored my domains, which contained code like this in the Apache config:

AuthType Digest
AuthName beergeekinc.com
AuthDigestFile /home/USERNAME/domains/DOMAIN.COM/etc/dav.digest.passwd

From what I can tell, AuthDigestFile is no longer used in Apache 2.2:

http://httpd.apache.org/docs/2.0/mod/mod_auth_digest.html
http://httpd.apache.org/docs/2.2/mod/mod_auth_digest.html

The new keyword appears to be AuthUserFile, which is part of mod_authn_file:

http://httpd.apache.org/docs/2.2/mod/mod_auth_digest.html

It might be necessary to test on the Apache version while restoring the virtual servers (and while adding those directives if it's not already doing so).
