Help me dial-in curator_user priviliges

I’ve created ‘curator_user’ in readonlyrest.yml file, like this:

  - name: 'Curator User'
    auth_key: "myuser:mysecret"
    actions: ["indices:admin/types/exists","indices:data/read/*","indices:data/write/*","indices:admin/template/*","indices:admin/*"]

When Curator runs, I get an Unauthorized error. I started investigating and I can’t even access that index from curl:

$ curl -u myuser:mysecret -XGET

DELETE action, of course, is not allowed either… Why?

Here is the entire config:

readonlyrest.yml: |-
prompt_for_basic_auth: false
audit_collector: true


  - name: 'Localhost'
    hosts: []

  - name: 'Probes'

Hi @jdepaul,
The answer to your question is in the ES logs, look for “FORBIDDEN” and analyse the “ACT:” part.

Simone, thanks - that was a good clue. Working on that now…

So I keep getting this error in ES log:
[2019-04-01T17:45:41,264][INFO ][t.b.r.a.ACL ] [elasticsearch-client-7898cb4cb8-vtn2z] FORBIDDEN by default req={ ID:1578983330–50375367#32575, TYP:GetSettingsRequest, CGR:N/A, USR:[no basic auth header], BRS:false, KDX:null, ACT:indices:monitor/settings/get, OA:, DA:, IDX:_all, MET:GET, PTH:/_all/_settings?expand_wildcards=open%2Cclosed, CNT:<N/A>, HDR:{content-length=0, connection=keep-alive, content-type=application/json, Host=elasticsearch-client:9200, Accept-Encoding=identity}, HIS:[Localhost->[hosts->false]], [Probes->[actions->false]], [Admins->[ldap_authentication->false]], [Kibana Admin->[auth_key->false]], [Lander Account->[auth_key->false]], [Logstash User->[auth_key->false]], [Rover User->[auth_key->false]], [Curator User->[auth_key->false]], [Local Auth for admin->[groups->false]] }

I have this defined for the curator_user:

  • name: ‘Curator User’
    auth_key: “curator_user:******"
    actions: [“indices:admin/types/exists”,"indices:data/read/

I don’t know why it’s still FORBIDDEN



As you can see ROR cannot extract a user from the request because there is no Authorization header. You need to tell curator to use HTTP “Basic” auth.

Once you do that, you need also to review your actions rule, as some of the rules you write end in “/”, I guess you forgot the star, i.e. "indices:data/read/* " instead of “indices:data/read/”.

Once you fix your actions rule, observe curator’s traffic. There will be the “ACT:” field in ROR ES log lines, it will tell you what action is Curator requesting.

After some trial and error you will be able to obtain the list of actions that curator needs to do, and authorize it for those only.

Your guidance was very good on this, thank you very much - got it all ironed out now. Grazie benne!
