Create new Index Pattern from console

I use the Kibana API for this: https://www.elastic.co/guide/en/kibana/master/saved-objects-api-create.html
And it wok. But after installing plugin Searchguard , it don't work. Need autorization.
I try:

1)Authenticate against Kibana:

$ curl -XPOST -D- 'http://localhost:5601/api/v1/auth/login'
-c /tmp/sg_cookies
-H 'Content-Type: application/json'
-H 'kbn-xsrf: true'
-d '{"username":"user","password":"password"}'

2)Create an index pattern via the Kibana API:

$ curl -XPOST -D- 'http://localhost:5601/api/saved_objects/index-pattern'
-b /tmp/sg_cookies
-H 'Content-Type: application/json'
-H 'kbn-xsrf: true'
-d '{"attributes":{"title":"logstash-*","timeFieldName":"@timestamp"}}'

But Authenticate don't work(

Help me please, what am I doing wrong?

SearchGuard is not an Elastic-supported plugin. If you need support with SearchGuard you may want to post in their Google Group.

Ok, Thank you!
