HELP

Is possible to configure LDAP authorization without UI. I want to automate this through ansible and have been looking into the REST APIs but am stuck.

Thanks for any advice.

Everything in graylog web is operated by API, so it should work. Check Rest API Browser to find LDAP section:
https://docs.graylog.org/en/4.0/pages/configuration/rest_api.html

Which graylog version do you use?

Hi @mbank59 ,
I’m also a big fan of ansible.

Here is a test bash script I’ve created for you. It gets User role id, creates new Active directory service, and active it.

  • Please update it for your purposes. Replace 172.28.128.15:9000 with your address of graylog.
  • Use basic auth, token, or session auth for authentication (I used basic for simplicity).
  • You can replace -H 'Authorization: Basic BASE64PASSWORD' with -u admin:PASSWORD if you want to use password directly in cmd
  • Change also parameters for your real LDAP server.
  • If you want to assign 2 or more default roles at once, include their id in parameter default_roles, separated by comma.
#!/bin/bash
# Get id of Role (Reader)
ROLE="Reader"
ROLEID=$(curl -s -X GET -H 'Authorization: Basic BASE64PASSWORD' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'X-Requested-By: cli' 'http://172.28.128.15:9000/api/authz/roles?page=1&per_page=50&sort=name&order=asc' | jq -r '.roles[] | select(.name=="'"$ROLE"'") | .id')

# Create new Active Directory service, set default_roles (Reader role id) and return backend id
NEWLDAPSERVICEID=$(curl -s -X POST -H 'Authorization: Basic BASE64PASSWORD' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'X-Requested-By: cli' 'http://172.28.128.15/api/system/authentication/services/backends' --data-raw '{"title":"Active Directory","description":"Description of service","default_roles":["'"$ROLEID"'"],"config":{"servers":[{"host":"ldap.domain.com","port":636}],"system_user_dn":"admin","system_user_password":"password","transport_security":"tls","type":"active-directory","user_full_name_attribute":"displayName","user_name_attribute":"userPrincipalName","user_search_base":"DC=domain,DC=com","user_search_pattern":"(&(objectClass=user)(|(sAMAccountName={0})(userPrincipalName={0})))","verify_certificates":false}}'|jq -r '.backend.id')

# Activate created Active Directory service by backed id
curl -s -X POST -H 'Authorization: Basic BASE64PASSWORD' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'X-Requested-By: cli' 'http://172.28.128.15/api/system/authentication/services/configuration' --data-raw '{"active_backend":"'"$NEWLDAPSERVICEID"'"}'
