@J. D. Bacolod
Can you post content of knox_sample and default topologies? 404 error show topology deployment issue and 401 means problem authenticating. You can check if Knox and Demo LDAP is working properly by logging in to Knox Host and issue below command: curl -iku admin:admin-password -X GET 'https://localhost:8443/gateway/admin/api/v1/version' This should return Knox Server version, something similar to below: HTTP/1.1 200 OK

@Baruch AMOUSSOU DJANGBAN Apache Knox is sort of Reverse Proxy which seats on Security Perimeter behind firewall and provide single point of access to underlying Hadoop services. An User will authenticate to Knox which can be configured to use Active Directory/LDAP/SAML-Based Identity Provider. Once User is authenticated with Knox, Knox will use it's own Kerberos Keytab to authenticate with other Hadoop services securely.
Note: Apache Knox is not alternative to Kerberos.

Apache Knox uses Shiro for LDAP authentication. You can put the details of your LDAP server and port in topology file. Knox will use the LDAP Server IP Address and Port to communicate. If you are using OpenLDAP to authenticate, you can safely stop Demo LDAP service in Knox.
Yes you need to install openldap, openldap-clients, and openldap-servers package.

The earlier created local Ambari "ambari_admin" user should exist even after ldap sync. Please select "All" as Type in Manage Ambari -> User+Group Management section, your user should show up there.

@Arun A K If you have existing admin user in your AD/LDAP, it will be override the existing Ambari admin user. This is known behaviour.
