Can't restrict API access by positional args via external_auth SaltStack

Question

I'm trying to restrict the calling state.apply only for specific SLS files via the pam module.

external_auth:
  pam:
    myuser:
      - '@runner':
        - jobs.list_job
      - '*':
        - test.ping
        - 'state.apply':
          args:
           - 'path/to/sls'

When I call the API via CherryPy API I get 401.

curl http://sat_master/run -H 'content-type: application/json' \
-d [{"tgt":"target","arg":["path/to/sls"],"kwarg":{"pillar":{"foo1":"bar1","foo2":"bar2"}},"client":"local_async","fun":"state.apply","username":"myuser","password":"<passwrod>","eauth":"pam"}]

What I also tried:

external_auth:
  pam:
    myuser:
      - '@runner':
        - jobs.list_job
      - '*':
        - test.ping
        - 'state.apply':
          args:
           - '.*'

external_auth:
  pam:
    myuser:
      - '@runner':
        - jobs.list_job
      - '*':
        - test.ping
        - 'state.apply':
          args:
           - '.*'
          kwargs:
           '.*' : '.*'

If I don't specify args it works:

external_auth:
  pam:
    myuser:
      - '@runner':
        - jobs.list_job
      - '*':
        - test.ping
        - state.apply

How do correctly do it?

Answer 1

The args field should be the field of the function object. I.e. :

Wrong:

'*':
  - state.apply:
    args:
     - 'path/to/sls'

The JSON equivalent

{
  "*": [
    {
      "state.apply": null,
      "args": [
        "path/to/sls"
      ]
    }
  ]
}

Right:

'*':
  - state.apply:
      args:
        - 'path/to/sls'

The JSON equivalent

{
  "*": [
    {
      "state.apply": {
        "args": [
          "path/to/sls"
        ]
      }
    }
  ]
}
