So, is it really enabled? Open a PHP shell and check the ini value:

$ php -a
Interactive shell

php > var_dump(ini_get('apc.enable_cli'));
php shell code:1:
string(1) "1"

Also check phpinfo output. If the module is loaded, you should see an apcu section

php > phpinfo(INFO_MODULES);
phpinfo()

apcu

APCu Support => Enabled
Version => 5.1.8
APCu Debugging => Disabled
MMAP Support => Enabled
MMAP File Mask =>

Thanks blizzz for that input!

I only checked that APCu was enabled with apc.enable_cli=1 through the standard phpinfo() page via HTTP Call.
As i checked it via var_dump it returned 0.

I moved the configuration from

/etc/php/7.0/cli/conf.d/20-apcu.ini -> apc.enable_cli=1

/etc/php/7.0/cli/php.ini

and it seems to work now regarding the CLI Log Entries.

But the user_ldap messages still occur! Any hints for fixing that?

That's dependent on your LDAP server. If it does not support paging, this is how it looks like, but it will still operate. Increase the Log level to not see those 🙊 Or is it supposed to do it?

Figured all out! Thanks for your support @blizzz
