'/admin/users/{id}/log_out.json' is not working

I’m still able to log out users via the api. Here is the curl command I used:

curl -i -sS -X POST "http://localhost:4200/admin/users/1/log_out.json"  \
-H "Content-Type: multipart/form-data"  \
-H "Api-Key: 64b901d2357526d1b6e8c439fd0570f9c585073e6160ae18cc82b7ac358d4893"  \
-H "Api-Username: blake.erickson" 

HTTP/1.1 200 OK

{"success":"OK"}

If you are still having issues, can you share more info about your api request with us?
