Reset Password for someone else.

Hello -

did anyone implemented reset password for other user (special/service identity) using default form. I am able to run the default password form as admin user, but anyone who is non-admin user is not able to see users getting loaded on form.

any idea or suggestion on how to handle password reset for any other user apart from self?

P.S - other user is nothing but some special identity owned by person who is trying to do password reset.
