PermissionsBukkit Help: Cannot use commands

Hi, I'm just starting out with servers and all that jazz. I have a plugin called PermissionsBukkit, and my Permissions.yml is empty. I'm having trouble using the commands that I should be able to use, so I need some help.

Code:

users:
    trio_pika:
        permissions:
            - permissions.*: true
        groups:
        -admin
       
    DurpySmurfy:
        permissions:
            - permissions.*: true
        groups:
        - admin
    DeadlyNightstep:
        permissions:
            - permissions.*: true
        groups:
        - admin

I think the reason it is not working is because your setting a boolean for all the permissions which you do not need. So to clarify remove the ': true or false boolean value ' so for instance, essentials.silentjoin: true would just be essentials.silentjoin.
