(Based on: https://forum.owncloud.org/viewtopic.php?t=2825) 1. Backup ../apps/user_ldap !!!!! 2. Decompress the attached file and replace the following files in the user_ldap directory: ./group_ldap.php ./lib/wizard.php ./templates/settings.php 3. In ownCloud go to the LDAP settings, "Groups" tab. As LDAP query use: (objectclass=zimbraDistributionList) 4. go to Advanced and select zimbraMailForwardingAddress as Group-Member association. 5. got to Expert and type uid as UUID 6. If something went wrong, replace ../apps/user_ldap with your backup.
