Accessing secure Geoserver layer with username password

I've created Users, Groups and Roles in Geoserver. And I set the user roles for my workspace.

• user1 can read


• user2 can write

And I want to access my layers as anonymous like this:

http:localhost:8080/geoserver/wms?request=GetCapabilities

This request returns 404 not found page.

I am using username password parameters but not working.

http:localhost:8080/geoserver/wms?request=GetCapabilities&user=some&password=some

If I login Geoserver admin panel and layer preview, I am accessing layer. If I logout, can not.
