You attempt to log in to vRealize Automation as an IaaS administrator and are redirected to the login page with no explanation.
If you attempt to log in to vRealize Automation as an IaaS administrator with UPN credentials that do not include the @yourdomain portion of the user name, you are logged out of SSO immediately and redirected to the login page with no explanation.
The UPN entered must adhere to a yourname.admin@yourdomain format, for example if you log in using email@example.com as the user name but the UPN in the Active Directory is only set as jsmith.admin, the login fails.
To correct the problem change the
userPrincipalName value to include the needed @yourdomain content and retry login. In this example the UPN name should be firstname.lastname@example.org. This information is provided in the log file in the log/vcac folder.
