Issue/Introduction
- SAML authentication in VMware Cloud Director users are consistently redirected to the external URL after successful SAML authentication, regardless of whether they initially accessed VCD via an internal or external URL.
Environment
VMware Cloud Director
Cause
- This discrepancy occurs because the SAML request from Cloud Director includes only a single AssertionConsumerService (ACS) URL, which defaults to the external URL.
- Cloud Director sends only one ACS URL (index 0) in the SAML request, configured to be the external URL.
- This configuration does not support multiple ACS URLs, resulting in the redirection issue.
Resolution
This resolution is based on the understanding that Cloud Director supports a single public ACS URL, which is reflected in the observed behavior.
To address this issue, the following steps are recommended:
-
Configure Cloud Director with a Single Public Address: Ensure that the public address configured in Cloud Director aligns with the primary access method (external URL) used by the majority of users.
-
Utilize Internal Access for Troubleshooting: Use internal URLs only for specific internal access or troubleshooting scenarios, as direct access via internal URLs is not recommended for general use.
