Apache Ranger REST API addUsersAndGroups returns 404 not found - apache-ranger

Question

We have installed Apache Ranger and the Web UI works fine, most of the REST API method works fine on both PublicAPIsv2 and RoleREST as per https://ranger.apache.org/apidocs/ui/index.html.
I can get “test_role” id by calling GET /public/v2/api/roles/name/test_role which returns the id 409.
I can get test_role content by calling GET /public/v2/api/roles/409
I can change test_role users list by editing the response I get from GET /public/v2/api/roles/409 and submitting it through PUT /public/v2/api/roles/409
The body is:
{
"id": 409,
"isEnabled": true,
"createdBy": "admin",
"updatedBy": "admin",
"createTime": 1598241102841,
"updateTime": 1601975068428,
"name": "test_role",
"options": {},
"users": [
{
"name": "test_user1”,
"isAdmin": true
},
{
"name": “test_user2”,
"isAdmin": true
},
{
"name": “test_user3”,
"isAdmin": false
}
],
"groups": [
{
"name": "test_group”,
"isAdmin": false
}
],
"roles": []
}
But calling PUT /public/v2/api/roles/409/addUsersAndGroups returns “404 not found”.
I tried with the same body as above as parameter, and also with:
{
"users": [
{
"name": “test_user4”,
"isAdmin": true
}
]
}
Would anybody know what is the correct body to send as parameter to:
/public/v2/api/roles/409/addUsersAndGroups?
Also, making a wrong call such as GET /public/v2/api/roles/409/addUsersAndGroups returns “405 method not allowed”. So I believe it shows the end point does exist. I’m not sure why calling PUT public/v2/api/roles/409/addUsersAndGroups with (probably) incorrect body returns “404 not found” and not an error message related to the wrong parameter.

Answer 1

It happens because Apache Ranger API documentation is wrong, remove the suffix /addUsersAndGroups of your endpoint and it will work.
Example: https://ranger_url/service/roles/roles/409
Where 409 is the role ID, as you're using on your example.
The body that is needed:
{
"name": "test_role",
"users": [
{
"name": "test_user1",
"isAdmin": true
}
]
}
