Help Wanted :-( Backends provided no user object for <userobject>

Hi Everybody,

I am facing a problem regarding NextCloud V 12.0.0.
The logfile nextcloud.log contains every 30 minutes this entry:
{“reqId”:“AQJBjq6XmMnv8sQvZiq6”,“level”:3,“time”:“2017-08-02T08:45:06+02:00”,“remoteAddr”:"",“user”:"–",“app”:“files”,“method”:"–",“url”:"–",“message”:" Backends provided no user object for DACA6CA8-5996-43D5-B450-B07117523916",“userAgent”:"–",“version”:“12.0.0.29”}

We use the LDAP extension; every user can login and there are no problems in our nextcloud, but the entry in the log makes me a little nervous. Federation is not available.
I have googled and found this posting:


seems to fix my problem, but there ist no lib/Activity/Listener.php .
In my system there are three Listener.php files and i am a little bit confused if this solutions works for nextcloud 12

Sorry, if my english is not that good => it has been years since i have to write something in english :wink:


Nextcloud version 12.0.0.29:
Operating system and version OpenSUSE 42.2:
Apache or nginx version Apache 2.4.23:
PHP version 7.0.7:
Is this the first time you’ve seen this error?: seems to occur since weeks

Can you reliably replicate it? (If so, please outline steps): every 30 minutes

The issue you are facing:
Every 30 minutes the log gets new entrys like
{“reqId”:“AQJBjq6XmMnv8sQvZiq6”,“level”:3,“time”:“2017-08-02T08:45:06+02:00”,“remoteAddr”:"",“user”:"–",“app”:“files”,“method”:"–",“url”:"–",“message”:" Backends provided no user object for DACA6CA8-5996-43D5-B450-B07117523916",“userAgent”:"–",“version”:“12.0.0.29”}

The output of your Nextcloud log in Admin > Logging:
{“reqId”:“AQJBjq6XmMnv8sQvZiq6”,“level”:3,“time”:“2017-08-02T08:45:06+02:00”,“remoteAddr”:"",“user”:"–",“app”:“files”,“method”:"–",“url”:"–",“message”:" Backends provided no user object for DACA6CA8-5996-43D5-B450-B07117523916",“userAgent”:"–",“version”:“12.0.0.29”}

The output of your config.php file in /path/to/nextcloud:

hi
even though nobody answered.
You should reset your mysql password, since you posted it in cleartext.
