This Zimbra drive for Nextcloud 9 and Owncloud 12.
It is based on the older version 8.7.10 because the newer versions of Zimbra aren’t working.
I edited the file info.xml to meet the Nextcloud version 12 and set the plugin version to 0.15 to prevent update warnings.
This is a edited version of Zimbra Drive version 8.7.10.
If you have a single Nextcloud setup, but multiple doains on the Zimbra Collaboration 8.7.10 site, you can enter a PreAuthKey for every domain.
You can find this version on Github: https://github.com/HansHM/zibradrive-multi-auth
