LDAP Connection error

Hello,

I do my connection like this

const client = ldap.createClient({
            url: `ldap://url:389`,
            reconnect: true
        });

        client.bind(_this.options.genericEmail, _this.options.genericPassword, err => {
            if (err) {
                callback(err);
            }
        });

And unbind after a search.

client.unbind( err => {
                        if (err) {
                            console.log(err);
                        }
                    });

But after a while on the development server, if it tries to connect again, I get this error and breaks the node server. I am running this application on a kubernetes environment.

events.js:167

Please help me fix this error.

Thank you.

I think this is the timeout error, I can’t test your code right now since my desktop is updating to F29 but should be able to later today.

In the meantime you can add a listener for the errors, so they hopefully won’t crash your application. Here is an example of listening for errors on the client.

// Return errors
client.on('error', error => {
    // Do something with the error
});

@tastypackets Thank you so much for detailed testing and explanation. Looks like switching to ldapts is the best option, and looks like no one maintains this code base. I will leave this open if at all someone wants to pick it up in the future. I would love to contribute, but my knowledge in LDAP is very very limited.
