New user without password

I am using Grafana v5.1.3 and would like to create users in grafana without password.

In the area of user management I am trying to create the user, but I
realized that the “password” field is mandatory, however I would like to
only create a user, since his authentication will be via LDAP. It is possible ?

Another thing that is happening is that even though I deselected the “Send invite email” option the user is not created directly. He keeps waiting for Pending Invites. Is it possible to disable this feature from sending an invite?

Use the allow_sign_up configuration to automatically create users when ldap is enabled.

There’s no way turning this off. Please note that you could manually approve pending invites by clicking on the pending invites button.
