Logging in to CMC Using Single Sign-on

When Single Sign-On (SSO) is enabled, you can log in to CMC without providing your domain user authentication credentials, such as user name and password. To use this feature, you must have an Enterprise License.
  • NOTE: You cannot use the IP address to log in to the SSO. Kerberos validates your credentials against the Fully Qualified Domain Name (FQDN).
Before logging in to CMC using SSO, make sure that:
  • You have logged in to your system using a valid Active Directory user account.
  • Single Sign-On option is enabled during the Active Directory configuration.

To log in to CMC using SSO:

  1. Log in to the client system using your network account.
  2. Access the CMC web interface by using: https://<cmcname.domain-name> For example, cmc-6G2WXF1.cmcad.lab,, where cmc-6G2WXF1 is the cmc-name and cmcad.lab is the domain name.
    • NOTE: If you have changed the default HTTPS port number (port 80), access the CMC web interface using <cmcname.domain-name>:<port number>, where the cmcname is the CMC host name for CMC, domain-name is the domain name, and port number is the HTTPS port number.
    CMC logs you in, using the Kerberos credentials that were cached by your browser when you logged in using your valid Active Directory account. If the login is unsuccessful, the browser is redirected to the normal CMC login page.
    • NOTE: If you are not logged in to the Active Directory domain and are using a browser other than Internet Explorer, the login is unsuccessful and the browser displays a only blank page.
