Drupal 7 + Services 3 : anonymous user can't access user/register endpoint (401 access denied) I'm using Services for providing an external webapp to register new user to the Drupal server.

I'm able to login from the webapp, create node and post comment.

But I can't have access to user registration.

My endpoint is configured and got all CRUD functionnality for user checked.

But when I try to acces it : http://localhost/rest/user/register

I got a 401 : ["Access denied for user anonymous"]

I guess I'm missing sone permissions, but I can't figure out which one ?

Could you please help me ?

Thanks in advance.

Well, apparently the 401 is a false error message.

I had an error in the data structure I posted to user/register, when I fixed it the 401 disappeared.

I still have an error on my user registration but this is now a 500.
