PHP Warning in log or occ command

hay gues,
bevor i start sorry for my bad English!

I have since yesterday an error in my logfile and on my commandline with occ.

PHP Warning: PHP Startup: Unable to load dynamic library '' (tried: /usr/lib/php/20170718/ (/usr/lib/php/20170718/ cannot open shared object file: No such file or directory), /usr/lib/php/20170718/ (/usr/lib/php/20170718/ cannot open shared object file: No such file or directory)) in Unknown on line 0

What should the error mean or what do I have to get away then? I also have a problem with the external storage app with a smb drive. Does that have something to do with it?

My last contributions:


thx for help

Looks like there’s a module missing… as stated in the error. What OS is that?

I had upgraded on Ubuntu 18.04.1 last week

The error message tells you that the module is not installed.‘’


Okay, i had now installed the ldap-php module now it is working!
But why nedd nextcloud this extention?

For authentification with LDAP.
