Active Directory AuthorizationException in elastic search - nest

Question

I am trying to use AD authentication. I am able to login successfully but i am not authorized to perform any query in marvel.
Everytime i execute query in marvel, i get the following error.Below are the details
{
"error": "AuthorizationException[action [indices:data/read/search] is unauthorized for user [shivang.Mittal]]",
"status": 403
}
elasticsearch.yml (C:\ES\elasticsearch-1.4.4\config)
shield:
authc:
realms:
active_directory:
type: active_directory
domain_name: tavant.in
url: "LDAP://DODC1.tavant.in:389"
user_dn_templates:
- "cn={0}, dc=tavant, dc=in"
group_search:
base_dn: "dc=tavant,dc=in"
files:
role_mapping: "C:/ES/elasticsearch-1.4.4/config/shield/role_mapping.yml"
role_mapping.yml (C:\ES\elasticsearch-1.4.4\config\shield).
Copied the same file in Node(C:\ES\elasticsearch-1.4.4\data\elasticsearch\nodes\0)
admin:
- "cn=users, dc=tavant,dc=in"
roles.yml
admin:
cluster: all
indices:
'*': all
UPDATE
As per Jaymode suggestion, I added the shield.auth: debug.
Below is the log (Which i thought would be useful)

Answer 1

EDIT 2: Based on your log message, you probably want to use the following mapping
admin:
- "CN=Users,CN=Builtin,DC=tavant,DC=in"
EDIT: I think I see your issue. In your role_mapping.yml you have:
admin:
- "cn=users, dc=tavant,dc=tavant"
It should most likely be:
admin:
- "cn=users,dc=tavant,dc=in"
I wonder if the DN you are using for role mapping is correct and is being retrieved. If you set debug logging the list of groups that are found for the user will be logged. To enable debug logging, edit the C:\ES\elasticsearch-1.4.4\config\logging.yml file:
...
logger:
# Add the line below
shield.authc: DEBUG
...
The log line will look something like this: the roles [], are mapped from these [active_directory] groups [ list of group DNs here ] for realm [active_directory/active_directory]
In that line you will find the actual list of group DNs that are retrieved. Also, your realm configuration can be simplified to the following:
shield:
authc:
realms:
active_directory:
type: active_directory
domain_name: tavant.in
url: "LDAP://DODC1.tavant.in:389"
The other settings actually appear to just specify what would be the default values if they are not specified.
