Server: Some contact birthdays shown multiple times

[danielbierstedt]

Steps to reproduce

I have no idea how to reproduce that. The source is an exported file from Owncloud.

Expected behaviour

One event shown per contact that has a birthday, anniversary or similar filled in the contacts.

Actual behaviour

Some contacts have 3 calendar events for a birthday, some have only one. The contact does not have duplicates, a sync to my mobile using caldav shows only one event for those, that show 3 in the webinterface.

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your instance's installation folder
The content of config/config.php:

<?php
$CONFIG = array (
'instanceid' => '***REMOVED SENSITIVE VALUE***',
'passwordsalt' => '***REMOVED SENSITIVE VALUE***',
'secret' => '***REMOVED SENSITIVE VALUE***',
'trusted_domains' =>
array (
0 => 'nas.mydomain.de',
),
'datadirectory' => '/path/to/data',
'overwrite.cli.url' => 'https://**_***********_/nextcloud',
'dbtype' => 'mysql',
'version' => '9.1.1.5',
'dbname' => 'dbname',
'dbhost' => 'localhost',
'dbport' => '',
'dbtableprefix' => 'oc_',
'dbuser' => 'dbuser',
'dbpassword' => '***REMOVED SENSITIVE VALUE***',
'logtimezone' => 'UTC',
'installed' => true,
'mail_smtpmode' => 'smtp',
'mail_smtpsecure' => 'tls',
'mail_from_address' => '***REMOVED SENSITIVE VALUE***',
'mail_domain' => 'gmail.com',
'mail_smtpauthtype' => 'LOGIN',
'mail_smtpauth' => 1,
'mail_smtphost' => 'smtp.gmail.com',
'mail_smtpport' => '587',
'mail_smtpname' => '***REMOVED SENSITIVE VALUE***',
'mail_smtppassword' => '***REMOVED SENSITIVE VALUE***',
'defaultapp' => 'calendar',
);

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your instance's installation folder

or

Insert your config.php content here
(Without the database password, passwordsalt and secret)
Are you using encryption: no

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your instance's installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM oc_appconfig WHERE appid = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.
Client configuration

Browser: Chrome

Operating system: Windows

CalDAV-clients: Windows / Linux -> Thunderbird Inverse SoGo Connector, Android -> EasyDAV

Same happened to me, maybe i know how to reproduce.
I had a buggy vcf File that i had to imports at least a dozen times b4 it finaly worked.
Sometimes i deleted the whole contacts, sometims i deleted just single entrys.
It seams to me like the entys for the complete delete somehow remain in the calendar, while the ones i deleted one by one dissapeard.

Same problem here, after deleting the whole address book and importing a backup of it all birthdays are shown multiple times.

[danielbierstedt]

As a workaround, I deleted the contacts birthdays calendar and re-created it. Cannot remember the occ command to do this right now...

[matzex]

After deleting the birthday calendar in the calendar app via the web gui, the command is:
./occ dav:sync-birthday-calendar username
Instead of "username" you have to insert the Nextcloud user for which the birthday calendar has to be created.

Sadly this can only be fixed by removing the calendar and add it again as described above. The cause is fixed.
