Hi Frank,
Kindly confirm if we are using external Platform Services Controller or a custom SSO domain?
To check if it is custom SSO
we can run the below command from vCenter appliance
cd /usr/lib/vmware-vmafd/bin ]# ./vmafd-cli get-domain-name --server-name localhost
If we are using an external Platform Services Controller (PSC), Single-Sign On (SSO) provider or have a custom SSO domain, toggle the Use Custom SSO Configuration switch to Yes.
a. Enter the PSC/SSO server or fully-qualified domain name (FQDN) or IP address.
b. If you are using the default PSC/SSO provider configuration, you do not need to complete the Advanced Options (optional) fields.
Complete the SSO Admin URL, SSO STS URL and Lookup Service URL only if you specified a custom configuration during the deployment of PSC or SSO provider.
For additional details regarding your PSC/SSO provider configuration, please see the vCenter Server vpxd.cfg file.
In vCenter Server Appliance 6.x, the vpxd.cfg file is located at /etc/vmware-vpx/.
In Windows Server, the vpxd.cfg file is located at C:\ProgramData\VMware\VMwareVirtualCenter\vpxd.cfg.
In vCenter Server 6.0, the vpxd.cfg file is located at C:\ProgramData\VMware\vCenterServer\cfg\vmware-vpx.
