Custom Joomla 4 Authentication Plugin

Post by mr412 » Fri Jun 02, 2023 2:55 pm

Hello

I need a custom authentication plugin to login with our ERP System. I tried this documentation:
https://docs.joomla.org/J4.x:Creating_a ... for_Joomla

This plugin does not work even without customizations.

from our ERP system it is relatively simple, only it seems to be very complicated in Joomla.

Credentials --> ERP REST --> return success = Login...

Does anyone have an example for Joomla 4? I have looked at all the Facebook Auth plugins, etc. but they are all too extensive to rebuild.

Thank you in advance!

The plugin if the example is very simple. Which type of error messages are displayed on the login page or written to the log file?

Which ERP system are you using? Which authentication protocols does it support?

thank you very much for the feedback.

even that doesn't work because the plugin can't be loaded.

Code: Select all

 public function onUserAuthenticate($credentials, $options, &$response) { 
  $response->status = Authentication::STATUS_SUCCESS;  
  }
The error message is:
Cant load Authentication Plugin 'authenticate'

I have now solved this by modifying the LDAP plugin. The difference is that the LDAP plugin registers itself as a provider. A tutorial for this would be ingenious.

I'd be interested in how exactly! I'm having the same issue with the example code; the plugin fails to load.

I get a page warning: JAuthentication: :authenticate: Failed to load plugin:

I have modified the plugin to accept ANY username and check for reverse password like the example, no other changes and it does authenticate.

There were a couple of problems with the code which I've fixed and updated that joomla docs page. I've tested it and it now seems to work ok.

The method has to be called onUserAuthenticate as it's called directly by Joomla. Joomla checks if that method exists and gives the error "Failed to load plugin" if it doesn't.

I'd be grateful if you guys gave it another try to check it's all ok now, thanks!

The plugin will load now and not give the error, however autnetication is not working. Using the exact example, unmodified, username exists and password is username reversed (not the actual password obviously) and the error:

Username and password do not match or you do not have an account yet
