Is it possible to update users details via Crowd REST API?

[Austin Wilburn]

There is a REST API call to update user details in Crowd Documentation, but it seems to want all user details passed in as well.

For example:

I want to update a user's email. I pass in the email as well as the username, but this overwrites all other details such as password, first name, etc because I did not pass them in as well.

Is there a way to update a user's email, without having to also pass in name, first name, password, etc?

If not, is there a way to just call currentPassword or something like that so that it just uses what is already stored on the server?

Thanks
