If you’re using Azure AAD as your federation SSO identity source, you might end up with the following error in your vcloud-container-debug.log pointing to an old token; Caused by: org.springframework.security.authentication.CredentialsExpiredException: Authentication statement is too old to be used with value 2019-08-12T08:12:11.298Z and Authentication request failed: org.springframework.security.authentication.AuthenticationServiceException: Error validating SAML message By default, Azure tokens have a fairly long lifetime, and VMware vCloud Director only accepts tokens with a maximum age…
