Ensuring a Secure Dell OpenManage IT Assistant Installation 225
Single Sign-On
The Single Sign-On option on Windows systems enables all logged-in users to
bypass the login page and access IT Assistant by clicking the IT Assistant icon
on the desktop. The desktop icon queries the registry to see if the Automatic
Logon with current username and password option is enabled in Internet
Explorer. If this option is enabled, then Single Sign-On is executed;
otherwise, the normal login page will be displayed. NT LAN Manager
(NTLM) authentication must not be disabled on the Windows network.
To enable the Automatic Logon with current username and password option,
perform the following steps in Internet Explorer:
1
Click Internet Options on the Tools menu.
2 Click the Security tab.
3 Select the security zone that the IT Assistant system falls within, that is,
Trusted sites and click Custom Level .
4 In the Security Setting dialog-box, under User Authentication , select the
Automatic Logon with current username and password .
5 Click OK twice, and restart Internet Explorer.
For local system access, you must have an account on the system with the
correct privileges (User, Power User, or Administrator). Other users are
authenticated against Microsoft Active Directory.
