courier-authdaemon not enabled by default to start

[JR]

The service authdaemond is not started by default at startup.
I had to use the following command so the service was started at startup :
$> sudo systemctl enable courier-authdaemon.service

Then the courier-imap with no particular authentification (ie through authdaemon) method was able to work perfectly!

To give more details, the error encountered was that I wasn't able to use the imap over ssl (although it worked perfectly up to 15.10 with nothing special to do)
In /var/log/syslog, the logged lines that appeared each time my mail client was trying to access to the local imap server were:
imapd-ssl: authdaemon: s_connect() failed: No such file or directory
imapd-ssl: LOGIN FAILED, user=JR, ip=[::ffff:192.168.1.254]
imapd-ssl: authentication error: No such file or directory

The release is:
Description: Ubuntu 16.04 LTS
Release: 16.04

I expected that the service was started automatically at startup.
What happened instead was it was not enabled, leading to this mess on my kubuntu installation.

So if the package's maintainer could check whether on a usual install( maybe this happened only on my computer) this service was enabled by default, that could help other people.

what on earth does this have to do with xorg?

Deeply sorry for the wrong assignment. Anyway the description reported the actual package.
