Discussion

Passwords need to be protected at all times, and encryption is the standard method for protecting passwords during transmission. Application servers have the capability to use LDAP directories for authentication. If LDAP connections are not protected during transmission, sensitive authentication credentials can be stolen. When the application server uses LDAP, the LDAP traffic must be encrypted.

Check Content

Confirm the Nutanix Envoy Reverse Proxy is set to use encryption when using LDAP.

1. Log in to Prism Element.
2. Click the gear icon in the upper-right corner.
3. Navigate to Authentication settings.
4. Verify an Active Directory or OpenLDAP server is on the directory list.

If an Active Directory or OpenLDAP servers are not using ports 636 or 3269, which are SSL encrypted, this is a finding.
