Description
Both the Universal Control Plane (UCP) and Docker Trusted Registry (DTR) components of Docker Enterprise leverage the same authentication and authorization backplane known as eNZi. The eNZi backplane provides automated mechanisms for supporting account management functions and allows for LDAP integration in UCP and DTR. While eNZi includes its own managed user database, it is recommended that LDAP integration be configured to more completely satisfy the requirements of this control. Satisfies: SRG-APP-000023, SRG-APP-000405, SRG-APP-000404, SRG-APP-000403, SRG-APP-000401, SRG-APP-000397, SRG-APP-000392, SRG-APP-000148, SRG-APP-000141, SRG-APP-000391

Verify that LDAP integration is enabled and properly configured in the UCP Admin Settings and verify that the LDAP/AD server is configured per the requirements set forth in the appropriate OS STIG. via UI: In the UCP web console, navigate to "Admin Settings" \| "Authentication & Authorization" and verify "LDAP Enabled" is set to "Yes" and that it is properly configured. If it is not set to yes and if the LDAP server is not configured then this is a finding. via CLI: Linux (requires curl and jq): As a Docker EE Admin, execute the following commands from a machine with connectivity to the UCP management console. Replace [ucp_url] with the UCP URL, [ucp_username] with the username of a UCP administrator and [ucp_password] with the password of a UCP administrator. AUTHTOKEN=$(curl -sk -d '{"username":"[ucp_username]","password":"[ucp_password]"}' https://[ucp_url]/auth/login \| jq -r .auth_token) curl -sk -H "Authorization: Bearer $AUTHTOKEN" https://[ucp_url]/api/ucp/config-toml Look for the "backend" entry under the "[auth]" section in the output, and verify that it is set to "ldap". *NOTE: For security reasons, the "[auth.ldap]" section is not stored in the config file and can only be viewed from the UCP Admin Settings UI.

in the appropriate OS STIG.

In the UCP web console, navigate to "Admin Settings" | "Authentication & Authorization" and verify "LDAP Enabled" is set to "Yes" and that it is properly configured.

If it is not set to yes and if the LDAP server is not configured then this is a finding.

via CLI:

Replace [ucp_url] with the UCP URL, [ucp_username] with the username of a UCP administrator and [ucp_password] with the password of a UCP administrator.

AUTHTOKEN=$(curl -sk -d '{"username":"[ucp_username]","password":"[ucp_password]"}' https://[ucp_url]/auth/login | jq -r .auth_token)
curl -sk -H "Authorization: Bearer $AUTHTOKEN" https://[ucp_url]/api/ucp/config-toml

Look for the "backend" entry under the "[auth]" section in the output, and verify that it is set to "ldap". *NOTE: For security reasons, the "[auth.ldap]" section is not stored in the config file and can only be viewed from the UCP Admin Settings UI.

If the "backend =" entry under the "[auth]" section in the output is not set to "ldap", then this is a finding.
