Security.yml is_secure false not working

i'm working in a webservice built on top off symfony framework.

Lately i was trying to make curl requests to a module but it gave me 500 error code reply asking for login and password, i looked inside module and it had the config folder with the file security.yml 开发者_如何转开发with this contents :

default:
  is_secure: false

What's wrong? why i can't make curl requests to this module?

I am not sure if 'default' is acceptable? Have you tried 'all' instead?

What about 'on' and 'off'?
