System Admin / EPM update seems to set provisauth to both

With some recent update of the non commercial System Admin module the provisioning endpoints are configured for authentication (happened in our system with System Admin 15.0.21.75 / EPM 15.0.41.4). The reason seems to be that in the MySQL table 'sysadmin_options' the key 'provisauth' is set to 'both' which creates blocks like these in /etc/httpd/conf.d/chmoozecom.conf | ssl.conf

<Directory /tftpboot/>
  AuthType Basic
  AuthName Restricted
  AuthUserFile /etc/httpd/provis.http.auth
  Require valid-user
</Directory>

Setting the key back to 'none' fixes the problem after updating the port configuration in  the System Admin module.

I do not think this is a desired behavior after an update. It should be fixed as it breaks provisioning by rejecting any request without username and password.
