OpenFire > Logout User via PHP Script

I'm using OpenFire 3.10.0 on RHEL 7

I'm registering users programatically via "userService" plugin

Similarly, is there a plugin or script to login& logout users via PHP script?

I tried http://server.com/plugins/userService/userservice?type=disable&secret=xxxx&username=spark1

Works fine, but it does not logout the users, it rather disables it.

Any points are appreciated.

Thanks!
