Windows NT LAN Manager (NTLM) authentication limitation
Dell OpenManage Power Center supports Kerberos SSO for Windows domain user authentication. To
enable this feature, OpenManage Power Center is configured to support the Windows integrated
authentication option which includes two authentication mechanisms: Kerberos and NTLM .
NTLM is not supported in OpenManage Power Center. If the client’s web browser uses NTLM to
authenticate domain users for OpenManage Power Center, there are some limitations.
The web browser displays a message box requiring a Windows user name and password.
• If you click OK after entering a user name and password, whether the information is correct or not,
the OpenManage Power Center login page is displayed and requires you may have to authenticate
through the login page.
• If you click Cancel, an HTTP Status 401 failure displays, and you cannot log into Power Center.
See Troubleshooting for more information on how to resolve this issue.
Logging out
To log out of Dell OpenManage Power Center when not logged in through Kerberos SSO, click Logout at
the upper right corner of the management console.
When logged in through Kerberos SSO, close the web browser or the OpenManage Power Center
management console to log out. Clicking Logout does not work.

• Administrator: All privileges
