Troubleshooting Security Plugin Issues

Please find the clear question
I am buidling a setup where there are three components:

  1. Keycloak as An IDP using openid connect , as well as client authentication method as client_secret.
  2. Opendistro security plugin with JWT token configuration.
  3. Python code trying to make an API call from access token got through curl command.

OpenDistro security plugin configuration:

---

---

# This is the main Open Distro Security configuration file where authentication
# and authorization is defined.
#
# You need to configure at least one authentication domain in the authc of this file.
# An authentication domain is responsible for extracting the user credentials from
# the request and for validating them against an authentication backend like Active Directory for example.
#
# If more than one authentication domain is configured the first one which succeeds wins.
# If all authentication domains fail then the request is unauthenticated.
# In this case an exception is thrown and/or the HTTP status is set to 401.
#
# After authentication authorization (authz) will be applied. There can be zero or more authorizers which collect
# the roles from a given backend for the authenticated user.
#
# Both, authc and auth can be enabled/disabled separately for REST and TRANSPORT layer. Default is true for both.
#        http_enabled: true
#        transport_enabled: true
#
# For HTTP it is possible to allow anonymous authentication. If that is the case then the HTTP authenticators try to
# find user credentials in the HTTP request. If credentials are found then the user gets regularly authenticated.
# If none can be found the user will be authenticated as an "anonymous" user. This user has always the username "anonymous"
# and one role named "anonymous_backendrole".
# If you enable anonymous authentication all HTTP authenticators will not challenge.
#
#
# Note: If you define more than one HTTP authenticators make sure to put non-challenging authenticators like "proxy" or "clientcert"
# first and the challenging one last.
# Because it's not possible to challenge a client with two different authentication methods (for example
# Kerberos and Basic) only one can have the challenge flag set to true. You can cope with this situation
# by using pre-authentication, e.g. sending a HTTP Basic authentication header in the request.
#
# Default value of the challenge flag is true.
#
#
# HTTP
#   basic (challenging)
#   proxy (not challenging, needs xff)
#   kerberos (challenging)
#   clientcert (not challenging, needs https)
#   jwt (not challenging)
#   host (not challenging) #DEPRECATED, will be removed in a future version.
#                          host based authentication is configurable in roles_mapping

# Authc
#   internal
#   noop
#   ldap

# Authz
#   ldap
#   noop

The application i am making query is as follows:

curl http://10.95.126.45:8080/auth/realms/demo/protocol/openid-connect/token \
-H 'Cache-Control: nocache' \
-H 'Content-Type: application/x-www-form-urlencoded' \

-d 'grant_type=client_credentials&client_id=elastic-2&client_secret=9e30fff3-ab4b-4b5d-89c9-0d94cf807483'

I am able to get the access token from this command. With jwt.io , verify the signature by putting the public key in keys section of realm in keycloak.

Verification of JWT Token using the same signing key in JWT configuration of opendistro

Then I am quering elastic search using a python requests library.
