can not do dat because:

As an additional information:
I can log in as admin. Ldap backend seems well configured, but no users are shown in users section.
I can log in as a user, but no shared folders are shown.

Seems you already have found #29544 where you had posted that info?

[fbassas]

I had found a similar old issue #28068 , and I posted there some info.
I don't know if that is what you mean.

[ghost]

Ok, so i think we can agree that it doesn't help to keep two issues about the same "Could not resolve CardDavBackend" message open until the reason and all of it's side-effects are known.

Additional side-note to:

I can log in as admin. Ldap backend seems well configured, but no users are shown in users section.

Its worth to check the release notes of the major release, there you can find a note about not showing up LDAP users:

https://doc.owncloud.org/server/10.0/admin_manual/release_notes.html#existing-ldap-users-only-show-up-in-the-user-management-page-and-the-share-dialog-after-being-synced

Maybe this info helps you to get your users showing up.

Hi, i have same issue and the way to solve it has been very easy:

• Download Owncloud 10.0.3 version.
• Descompress on a new folder.
• Copy your config/config.php file to new installation config folder (set correct permission).
• Config new installation folder on your web server domain config.
• Restart WebServer.

This issue could be for an old library not present in 10.0.3 version. That's all.

@fjavimartin Thanks for posting this additional info. You might want to post it in #28068 as well as that one is still open.

[ghost]

@fjavimartin Side note to your steps in #29544 (comment) :

You can't move an ownCloud installation to a new folder without doing any manual modifications in the database. Instead delete all files and folder except /data and /config and then extract the 10.0.3 archive into the existing folder.

Just for the record: we use OwnCloud here under Docker, and I've run into a very similar problem.

After putting OwnCloud in maintenance mode and upgrading the docker image, I've run ./occ upgrade inside the container. I've then hit a DB migration issue (solved with #28695 (comment)), and after that, I hit the issue mentioned here

After reading the thread here I realized the /apps directory of my installation was mount as an external volume in docker, so I could have had old files there. I solve it by doing the following:

• put OC in maintenance mode again
• rerun the container without the apps volume mounted, getting access to the "updated apps"
• move out the old apps, and copying the ones from inside the container to the host volume
• run the container back with the apps volume
• run ./occ upgrade again (here it asked to disable some apps manually)
• take out from maintenance mode

It's (more or less) clear that one should keep only /data and /config when upgrading OC, but this is kind of out of the user's direct control when running under docker. Maybe there could be a warning/instruction with different instructions in this case?
