When attempting to update / reconfigure the LDAP URL being used for vCenter Active Directly Identity Source (LDAP), the process fails.
vCenter Server 7.0
vCenter Server 8.0
vCenter Server workflow attempts to contact the currently configured LDAP URL during the reconfiguration process.
In the /var/log/vmware/sso/ssoAdminServer.log you see errors similar to:
Cannot configure identity source due to Failed to probe provider connectivity [URI: ldap://controller-1.domain.com ]; tenantName [vsphere.local], userName [domain\user] Caused by: Can't contact LDAP server.
Remove the currently configured ID source from vCenter and then re-add it using the new Domain Controller URL.
