Dell EMC iDRAC Service Module 3.5.1 User’s Guide

The single sign-on (SSO) feature enables an authenticated OS administrator to directly access the iDRAC web interface without requiring login of separate iDRAC administrator credentials. On installing this feature, a Program Menu shortcut that is called Invoke-iDRACLauncher on Microsoft Windows operating systems is created. On the Linux operating system, iSM creates a shortcut under Applications, where the user can double-click and launch the iDRAC dashboard. iSM provides a command-line interface that is called Invoke-iDRACLauncher on Microsoft Windows operating systems and Invoke-iDRACLauncher.sh on Linux operating systems.

Starting iSM 3.5, user can configure the iDRAC service module using IPv6 address. By default, the communication is established through IPv4. Upon failure, the communication is reattempted through IPv6. An error message is displayed, when the communication fails.

Users can choose from two types of privileges to log in to iDRAC.

• Read-Only user: An express or basic install of iSM installs iDRAC SSO launcher, enabling the Administrator to log in to iDRAC as a Read-Only user. Besides the ability to view component health status, logs, and inventory, few additional SupportAssist operations that are required by the service personnel are enabled.
• Administrative user: Installing this feature by selecting the Administrator privilege, enables the Host OS Administrator to log in to iDRAC as an Operator user. The user can perform all the operations as that of an iDRAC root user except configuring or deleting iDRAC users or clearing the Lifecycle Log.

Disable Single Sign-On into iDRAC from Host OS: The user can also opt to Disable this feature completely. When iSM is installed by disabling this feature, launching iDRAC GUI launcher launches the iDRAC login page with the default browser.

Following are the iDRAC GUI Launcher behavior with different OS-to-iDRAC Passthrustates:

• When OS-to-iDRAC Passthrough setting in iDRAC is disabled, Invoke-iDRACLauncher prompts if you want to enable OSBMC-Passthrough in USBNIC mode.
• When OS-to-iDRAC Passthrough setting is already configured in LOM mode, the iDRAC Launcher does not launch the iDRAC GUI.
• When OS-to-iDRAC Passthrough setting is disabled in iDRAC and Disable iDRAC Local Configuration using Settings is also disabled or lockdown mode is enabled in iDRAC, iDRAC GUI is not launched.
  NOTE When Local Configuration using Settings or Local Configuration using RACADM is disabled in iDRAC, iDRAC login screen is displayed.
