And forum not running after that while I not disable manually plugin via ./nodebb reset -p @nodebb/nodebb-plugin-node-ldap

NodeBB i run in docker like that

version: '3.5'

services:
  nodebb-forum:
    image: nodebb/docker:latest
    restart: unless-stopped
    volumes:
      - /projects/NodeBB/app:/usr/src/app
    ports:
      - "4567:4567"

NodeBB v 2.8.1 and nodebb-plugin-node-ldap v 2.0.2

Seems like ldap plugin is missing some error checks, can you try with @nodebb/nodebb-plugin[email protected] and see if you get anything in the nodebb logs?

@baris Yes, with 2.0.3 crashes disappeared and now in logs i see belowe:

(node:409) [LRU_CACHE_UNBOUNDED] UnboundedCacheWarning: TTL caching without ttlAutopurge, max, or maxSize can result in unbounded memory consumption.

Next step would be to check if the config is saved properly in the acp, that error indicates the plugin is unable to connect in this function.

adminClient: (callback) => {
            const tlsOptions = {'rejectUnauthorized': false}
            const client = ldapjs.createClient({
                url: master_config.server + ':' + master_config.port,
                tlsOptions: tlsOptions,
                timeout: 2000
            });
            client.on('error', error => callback(error));

            client.bind(master_config.admin_user, master_config.password, (err) => {
                if (err) {
                    return callback(new Error('could not bind with admin config ' + err.message));
                }
                callback(null, client);
            });
        },

@baris Thanks. I fix my ldap settings and it's worked.
But now i have another issue. New user creating everytime when I try auth for same user. It's creating username like username, username 0, username 1 and etc.
Should it works like that? How can i get user from ldap once and after that login under that user?

[baris]

Check your database key ldapid:uid and the user object for the nodebbldap:uid: fields. Do they have the correct ldap id?

Those are the fields used by the plugin to tell if a user with that id is already registered in nodebb.

I'm using postgresql and I can't find these keys anywhere
