We are changing our company name in a rebranding effort. We use Application Server Portal for our external website with the URL (i.e. www.company-abc.com). We have a two server setup (Infrastructure and Mid-Tier), with "company-abc.com" as our domain.
We are changing our name to (i.e. company-xyz). When we update our DNS, we can get to www.company-xyz.com, but when it redirects to Single Sign On, the URL displays "login.company.abc.com".
