Disabling Federated Login for vCenter is not a common workflow.
Federated Login for vCenter was designed to be a long-term replacement for the default vCenter login workflow in VMware Cloud on AWS. You must disable Federated Login for vCenter if you need to Configure SDDC Compliance Hardening in an SDDC where it has been enabled. Disabling Federated Login for vCenter requires you to reconfigure any Active Directory over LDAP settings you want to restore in vCenter.
Procedure
What to do next
After the Disable Federated Login workflow completes, reconfigure the Active Directory over LDAP settings for this organization. Follow the procedures in Add or Edit a vCenter Single Sign-On Identity Source to restore the configuration that was in place before you configured the SDDC for enterprise federation.
