Description of problem:
Calling /users/<user_id>/sshpublickeys does not return stored ssh keys for non admin user, but for admin user.

Version-Release number of selected component (if applicable):
ovirt-engine-restapi-4.2.6-0.1.el7ev.noarch

How reproducible: always


Steps to Reproduce:
1. add new user to engine, set UserRole permission
2. log into VM portal
3. go to Options dialog and save public ssh key
4. ssh key is loaded in dialog also after logout/login
5. call api:
curl -k -u admin@internal:password -H "Prefer: persistent-auth" https://engine/ovirt-engine/api/users/<user_id>/sshpublickeys


Actual results: no ssh key returned
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ssh_public_keys/>


Expected results: stored ssh key returned, e.g.:
<ssh_public_keys>
    <ssh_public_key href="/ovirt-engine/api/users/49210e66-7c2c-4ce9-87fa-e8c3609dd8dd/sshpublickeys/e52ddd30-f6a2-4d8f-b305-1dde462870b7" id="e52ddd30-f6a2-4d8f-b305-1dde462870b7">
        <content>ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDDN...</content>
        <user href="/ovirt-engine/api/users/49210e66-7c2c-4ce9-87fa-e8c3609dd8dd" id="49210e66-7c2c-4ce9-87fa-e8c3609dd8dd"/>
    </ssh_public_key>
</ssh_public_keys>

6. log into webadmin portal as admin user
7. go to Options dialog and save public ssh key
8. call again api for the non admin user

Actual results: stored ssh key for admin user is returned, instead the one for non admin user



Additional info:
No error in engine log.
I see the ssh key in Options dialog (VM portal) and also in database for the non admin user:

select p.user_id, u.username, p.ssh_public_key from user_profiles p join users u on (u.user_id = p.user_id)  where u.user_id='49210e66-7c2c-4ce9-87fa-e8c3609dd8dd';
user_id                              | username | ssh_public_key
