core-8.7.80 breaks LDAP groups on Debian 9 /w OpenLDAP

  • After upgrading to core-8.7.80, Kopano is no longer able to look up the group memberships of Kopano users + Kopano groups have no members (tested on Debian 9 AMD /w OpenLDAP). Works perfectly if I restore the VM with a snapshot to roll back to the previous version of Kopano.

    kopano-cli --user “chris”

    That works for me with

  • Apparently the cause were old ldap*.cfg config files. I have restored the most recent ldap.cfg and ldap.openldap.cfg from /usr/share/kopano and applied the required changes, so I can connect to my LDAP again. That solved the issue.

  • Kopano

    That reads like you were doing adjustments to the ldap configuration below /usr/share. User modified files should always reside in /etc

  • Actually no. I am using the memberOf overlay in my OpenLDAP settings which require changes in ldap.openldap.cfg. However, after every core update I had my ldap.openldap.cfg overwritten in /usr/share/kopano which led me to the idea, to copy the ldap*.cfg files to /etc/kopano and change the file paths to /etc/kopano instead of using /usr/share/kopano.

    @chris said in core-8.7.80 breaks LDAP groups on Debian 9 /w OpenLDAP:

    Actually no. […] after every core update I had my ldap.openldap.cfg overwritten in /usr/share/kopano

    You are conflicting with yourself.

    I’ll repeat: you should only make adaptations to your ldap configuration in /etc/kopano, the default file to use there is /etc/kopano/ldap.cfg. This is also a topic in the Kopano admin manual at We have recently rewritten this to streamline the configuration process a bit.
