[Bug 2913] mod_auth_pam fallthrough always fails (because mod_auth_pam never returns PAM_USER_UNKNOWN)

Public bug report changed:

I encountered this same problem, so for those just searching for the workaround, I found the solution buried in the README file for the package libapache-mod-auth-pam 1.1.1-7.1 package.

The short answer is, mod_auth is handling your "require" statements *before* mod_auth_pam, so you have to tell it to give other modules a chance by setting "AuthAuthoritative Off".

The mod_auth_pam documentation says to use "AuthPAM_FallThrough on" to
allow other modules a chance to provide authentication info. That only
works if mod_auth_pam is handling requests *before* mod_auth.
