Basic realm="Authorization Required" after successful authentication

[Pierre de Soyres]

Hi,

I'm experiencing a strange behaviour when using Search guard on elasticsearch and kibana. I'm using

- Elasticsearch 5.5.0 with SearchGuard plugin 5.5.0-16

- Kibana 5.5.0 with SearchGuard plugin 5.5.0-4

To start exploring the searchguard capabilities, I followed the instructions and installed the provided demo (auto signed certificat and default users/password/roles) :

- run plugins/search-guard-5/tools/install_demo_configuration.sh

- start elasticsearch

- run sgadmin_demo.sh

- run kibana

When I connect to elasticsearch, I am asked to enter user/password, and everything works as expected : receiving right errors when authenticated user hasn't got rights for certain actions, etc...

When I connect to kibana, I am redirected to the SearchGuard login page. I enter the user/password (kibanaro/kibanaro or admin/admin), and for now all is ok.

But then comes my problem, I'm again asked to enter user/password with the browser built-in authentication popup. And there, I cannot authenticate with any password (admin/admin nor kibanaro/kibanaro nor kibanaserver/kibanaserver)

I used tcpdump and wireshark to see what's going on, and I could see that :

from login page : a POST to http://localhost:5601/api/v1/auth/login returns OK

Then a  GET to http://localhost:5601/ returns OK and kibana redirects to the default route

Finally the GET to http://localhost:5601/app/kibana returns an HTTP 401 with header Basic realm="Authorization Required"

Is there anything I missed ?

Here are the related informations :

-> sgconfig directory content which is exactlly what is procided by the plugin installation : attached file sgconfig.zip

-> result of a find_all query on the search_guard index : attached file searchguard.json

-> the elasticsearch conf :

######## Start Search Guard Demo Configuration ########

searchguard.ssl.transport.keystore_filepath: keystore.jks

searchguard.ssl.transport.truststore_filepath: truststore.jks

searchguard.ssl.transport.enforce_hostname_verification: false

searchguard.ssl.http.enabled: true

searchguard.ssl.http.keystore_filepath: keystore.jks

searchguard.ssl.http.truststore_filepath: truststore.jks

searchguard.authcz.admin_dn:

  - CN=kirk,OU=client,O=client,L=test, C=de

cluster.name: searchguard_demo

network.host: 0.0.0.0

######## End Search Guard Demo Configuration ########

-> the kibana conf :

searchguard.multitenancy.enabled: true

elasticsearch.requestHeadersWhitelist: ["sg_tenant"]

elasticsearch.username: "kibanaserver"

elasticsearch.password: "kibanaserver"

elasticsearch.url: "https://localhost:9200"

elasticsearch.ssl.verificationMode: none

Any help would be appreciate.

I attach also the tcpdump wireskark export.

The problem here is this line kibana.yml:

elasticsearch.requestHeadersWhitelist: ["sg_tenant"]

The whitelist if Kibana contains the "Authorization" header by default.  However, if one manually changes the white list, "Authorization" is not added by default again, so you need to manually add it like:

elasticsearch.requestHeadersWhitelist: ["Authorization", "sg_tenant"]

then it should work. Sorry if the docs are not clear enough here, we'll fix this.

[Pierre de Soyres]

I confirm that it works when adding "Authorization" to the requestHeadersWhitelist.

Thank you for helping.

Pierre
