Nothing interesting.

@blizzz looks like something for you.

@greendruid seems to me to be either an issue with the installation (not all files), or the autoloader.

On Admin → Server Settings, what do you see in Security & setup warnings?

Can you do other things, like enabling apps? This also uses the OCP\JSON class.

[greendruid]

@blizzz , hi
I download package from official site. Then I follow the instruction (link: https://docs.nextcloud.com/server/11/admin_manual/installation/source_installation.html )
In "Security & setup warnings" only next message: "No memory cache has been configured. To enhance your performance please configure a memcache if available..." But I think that notification is not an error. (Right?)
I can enable/disable application & create users & upload/download/remove files.

[greendruid]

I found the solution! :) I just added the one string to the files and all ok!
PATH: /apps/user_ldap/ajax/
FILES: clearMappings.php, deleteConfiguration.php, getConfiguration.php, getNewServerConfigPrefix.php, setConfiguration.php, testConfiguration.php, wizard.php
STRING: require_once($_SERVER['DOCUMENT_ROOT'].'/lib/base.php');

clearMappings.php for example:

<?php
require_once($_SERVER['DOCUMENT_ROOT'].'/lib/base.php');
/* ... CUT COMMENTS ... */
use OCA\User_LDAP\Mapping\UserMapping;
use OCA\User_LDAP\Mapping\GroupMapping;
...

This really should not be necessary, but then the issue is rather somewhere with the server setup. Likely this will haunt you after updates.

As it works for now, I close it.

Thanx a lot @greendruid on Nextcloud 16.0.1 wirh Nginx your line is also needed!
If not, you can not setup LDAP becaus there is nor responce on the adon, nothing work.
