We want to keep using the OKTA setup we have.
If I follow the instructions from https://techdocs.broadcom.com/us/en/ca-enterprise-software/layer7-api-management/api-developer-portal/saas/set-up-and-maintenance/set-up-custom-domain-names.html we get an error when trying to generate the CSR.
Release : 5.1.2
Saas Portal migration to k8s requires a code changes to be implemented in order to support custom domain
SaaS Portal 5.2.2 will have the code changes to support custom domain
Until the custom domain is set up, they cannot use a custom domain URL as ACS URL. You will need to use the normal Portal URL (without custom domain) as the ACS URL and change it to the custom URL when it becomes available in 5.2.2.
