"Service not available" Error with IMAP authentication module

[Wolfgang Rosenauer]

The middleware is most likely not listening on port 8009 or the Apache proxy configuration is not correct.
With "listbundles" or "getmissingservices" you could get an idea but only if _something_ starts. If not you'll just get error messages and need to read the different logs in /var/log/open-xchange carefully since they typically contain the real error somewhere.

Hello,

I'm trying to set up a single "proof of concept" test server to see how OX can work with our Dovecot cluster.

I'm using this document:

https://oxpedia.org/wiki/index.php?title=AppSuite:Open-Xchange_Installation_Guide_for_Debian_8.0

The installation went smooth and I can see the front-end website in the browser, but the login page is not being shown, instead I get:
"Connection error: the service is not available right now, Retry"

Because I want to authenticate with our IMAP backend i did not install the database authentication package but open-xchange-authentication-imap, using the following adjusted command from the documentation:

apt-get install mysql-server open-xchange open-xchange-authentication-imap open-xchange-grizzly open-xchange-admin open-xchange-appsuite open-xchange-appsuite-backend open-xchange-appsuite-manifest


I'm Googling around for this error but the cases I find don't seem to apply to my situation.
I'm not sure if i'm facing a problem with mod_proxy or with a connection/config problem to my IMAP backend.
I can telnet to the IMAP server from this OX server so that should all be fine.

I've successfully setup OX like this before 1 1/2 year ago so I'm familiar with the process.
But I guess now I'm missing something somewhere, I hope someone can give a litte insight.

I've added my proxy_http, vhost and imapauth.properties configuration to this post below.

Thanks in advance,
Marcel de Cocq.
