Apache upgrade 2.2 -> 2.4 and "PerlAuthenHandler Authen::Simple::IMAP"

[Jobst Schmalenbach]

I posted this first on the Apache mailing list, one person mentioned as this is 
mod_perl related I should post it here, so here it is.

I have just started upgrading all of my CentOS servers from 6.X to 7.X, with 
that Apache gets upgraded from 2.2 to 2.4, but it seems mod_perl has not 
increased the version number.

While I have fixed most of the issues realted to the upgrade of Apache one I 
cannot solve is the "PerlAuthenHandler Authen::Simple::IMAP" in .htaccess files.

I use this rather frequently on many machines as it is real easy for me to look 
after this.

Using apache 2.2 this used to work like a charm with an .htaccess file in the 
directory to protect:

    satisfy any
    Order deny,allow
    deny from all

    AuthName "Protected by IMAP credentials"
    AuthType Basic
    require user USER1 USER2
    PerlAuthenHandler Authen::Simple::IMAP
    PerlSetVar        AuthenSimpleIMAP_host     "CENTRAL.IMAPS.SERVER.HOST.NAME"
    PerlSetVar        AuthenSimpleIMAP_protocol "IMAPS"

    allow from localhost
    allow from THESERVER

I re-wrote this for apache 2.4 (not repeating the perl stuff which is the same 
in both) but same .htaccess file

   <RequireAll>
     Require user USER1 USER2
     # do not turn this off, or else this will not work.
     Require ip 127.0.0.1
     Require host localhost
     Require host THESERVER
   </RequireAll>

In the server's httpd.conf file I have:

   PerlRequire /etc/httpd/conf/startup.pl

which contains this:

   #!/bin/env /usr/bin/perl
   use strict;
   use warnings;
   use Authen::Simple::IMAP;
   1;

This loads with no error messages (this also means mod_perl is working).

The problem really is:

  ==> error_log <==
  failed to resolve handler Authen::Simple::IMAP
  failed to resolve handler Authen::Simple::IMAP
  failed to resolve handler Authen::Simple::IMAP
  failed to resolve handler Authen::Simple::IMAP

The browser page displays a "Secure connection failed" which is crap as the 
certificate and everything is in perfect condition.


How can I make this work with apache 2.4?
What am I doing wrong?


thanks
Jobst
