Hello 
New phone, not previously synced. No errors or warnings but no contacts synced from phone to server or server to phone. Calendar sync not investigated. Manufacturer’s Contacts app.
Same emailarray (PolarisMail) server syncs using both Thunderbird 17.0.11esr with sogo-connector-17.0.2 and using Debian 8 Jessie’s Icedove with sogo-integrator-31.0.1.

Hello,
The logs you have posted are from the second synchronization, which doesn’t detect any changes to the first synchronization, so it doesn’t do anything.
Please provide more information: What exactly happens (including logs; don’t forget to disable automatic sync so that you can manually control when synchronization is started) when you add a contact on the phone and then synchronize? What happens if you add a contact on the server and then synchronize?
Thanks rfc2822
Sorry for the testing incompetence.

Checked the CardDAV address book in the web interface. The new contact was present.
One detail that may be relevant. Thunderbird/sogo-connector is configured with a different URL than the one shown in DAVdroid’s log: https://charlesXXXXXX--org.emailarray.com/modules/carddav/addressbook.php/addressbooks/charles%40charlesXXXXXX.org/charles-XXXXXX-5/
Incidentally, I was unable to reply here using Iceweasel; Opera was OK.

https://charlesXXXXXX--org.emailarray.com/modules/carddav/addressbook.php/addressbooks/charles%40charlesXXXXXX.org/charles-XXXXXX-5/
This seems to be the cause of your problem. There are two different CardDAV providers: /modules/carddav/addressbook.php and /dav.php/addressbooks. Thunderbird synchronizes with the first one, DAVdroid with the second one.
There seems to be a problem with your setup. Are the multiple CardDAV services running intentionally? If yes, which one is configured as well-known URL?
Thanks rfc2822
I have mailed your question to the service provider, Polaris mail. They are normally very responsive but have not responded about this issue, perhaps because their recommended CardDAV app is Caldav Sync Free Beta (now CalDAV Sync Adapter 1.8.1 but that fails on my phone with “Install error. Failed to install due to an unknown error”).

PolarisMail replied:
Hi Charles,
All URL’s have the same provider as the back-end, it’s just that different applications like to use different URL’s. What happens if you try to configure DAVdroid with the Thunderbid URL ?
George
Is it possible to try the configuration George suggested?
@Charles said:

In my opinion, this is a very strange way to configure CalDAV/CardDAV. But why not …
Is it possible to try the configuration George suggested?
You can enter the full URL directly and then choose the appropriate address book in the Setup dialog.
I’d rather suggest to use DAVdroid’s URLs in Thunderbird, as those are the ones configured by the provider’s well-known URLs (otherwise, DAVdroid wouldn’t have found them).

Thanks rfc2822
First, as you suggested, I configured the Thunderbird address book with the URL auto-detected by DAVdroid (https://al.emailarray.com/dav.php/addressbooks/charles%40XXXXXX.org/AddressBook/) and synchronised. The address book entries were replaced by a single test entry, created on the phone. Reverted and got the full address book back.
Second I configured DAVdroid with the URL used in Thunderbird (https://charlesXXXXXX--org.emailarray.com/modules/carddav/addressbook.php/addressbooks/charles%40XXXXXX.org/charles-m-atkinson-5/) and syncronised.
That failed:

That means that you have to disable pre-emptive authentication (= enable Digest authentication) in DAVdroid (use the checkbox in the Setup activity or in Account Settings).
Tentative conclusions:
- The two URLs do not connect to the same address book
Indeed, at least they behave in a different way.
- Whatever is at the URL used by Thunderbird is not compatible with DAVdroid
You have to disable pre-emptivation authentication.
- The defects are in the PolarisMail server configuration rather than DAVdroid
Partially. Theoretically, there could be more than one CardDAV service under different paths, but what’s the use of this? I guess it’s not intended (especially when they say that all use the same backend), but it could be possible.
Solved 
Disabling pre-emptive authentication resulted in synchronisation.
Thank you for all your help, rfc2822, especially as the irregularities were at the CardDAV server.

Sorry, I did not answer “Did you enter an email address or base URL in DAVdroid?”.
I entered Base URL: https://al.emailarray.com/dav.php
That URL came from PolarisMail’s http://wiki.polarismail.com/display/Support/Sync+contacts+and+events+via+CalDAV+(iOS%2C+Android%2C+Thunderbird%2C+eM+Client)+-+Basic
