Single Sign On
Though CMC is setup to allow Single Sign-On (SSO), the browser displays a blank page.
Only Mozilla Firefox and Internet Explorer browsers are supported at this time for SSO. Check the browser settings for the correct
setup. For more information, see the Configuring Browser for SSO Login section.
If the browsers are configured correctly, both browsers must allow you to log in without entering the name and password. Use the
Fully Qualified Domain Name (FQDN) for the CMC. For example, myCMC.Domain.ext/ in the Address bar of the browser. The
browser redirects you to the https (secure mode) and enables you to log in to the CMC. Both http and https are valid for the
browsers. If you save the URL as a bookmark, you do not have to any text after the last forward slash in the example. If you still
cannot log in using the SSO, see the Configuring CMC SSO or Smart Card Login for Active Directory Users section.
