Can't share file with other users

ℹ️ Support

Hi guys and girls,

Nextcloud version: 20.0.8
Operating system and version: CentOS Linux release 8.3.2011
Apache: 2.4.37-21
PHP version: 7.2.24
LDAP: IPA server: 4.8.4-7

I can authenticate without problem to my nextcloud system. The only time I notice a problem is when I attempt to share a file.

When I click on the sharing icon, I can see a user show up as a potential sharing user. However, if I click on that user, the sharing never happens, just an endless spinning icon on the browser. If I type the username completely, the same happen, just hangs and sharing don’t happens.

When I look at the logs, this seem to be the most likely cause:

==
Error user_ldap Attempt for Paging? 1

Have someone else faced a similar problem? The error “Critical extension is unavailable” imply a missing add-on, would this be correct and what add-on/extension would that be?

Steps to replicate it:

  1. Login to to nextcloud
  2. Create a file
  3. Attempt to share it with another user

The output of your Nextcloud log in Admin > Logging:

Hi William,

Please could you execute the following command via SSH and see, if the ldap extension is being listed?

Command:

php -m

If it is not listed, you can view a list of available php extensions with the following command:

dnf module list php

Look for ldap and then use the command:

dnf install {extension_name}

(Please remember to restart your Apache after installing new extensions)

You can also check your php.ini to see, whether the extension is enabled (remove the # in front of it)
