While trying to login and configure a vCenter Single Sign-On (SSO) 5.5 Identity Source, I received this error message.

Posted on Posted in vCenter Server Appliance
Issue:
clip_image001
Failed to connect to VMware Lookup Service
https://vCVA_IP_address:7444/lookupservice/sdk – SSL
certificate verification failed.
Fix:
You will need to toggle the certificate settings on the VMware vCenter Server Appliance (vCSA).

To toggle the certificate settings:

  1. Log in to the vCenter Server Appliance Web interface at https://hostname:5480/.
  2. Click the Admin tab.
  3. Regenerate certificates:
    • vCenter Server 5.1: Select Toggle certificate setting so that the Certificate regeneration enabled displays Yes.
    • vCenter Server 5.5: Select Yes under Certificate regeneration enabled.
  4. Reboot the vCenter Server Appliance.
  5. After the vCenter Server Appliance reboots, confirm that the Certificate regeneration enabled option is set to disabled.
Notes:

vCenter Server generates new default certificates using this option. For systems that use custom certificates, regenerate the certificates manually.
