We currently using default iLO 2 active directory logon schema. but we are not able to logginh using Domain name account format, John@domain.com or domain\John,
How should I set the iLO 2 that support this format?
iLO 2 supports using "@domain.com" in the search contexts The browser has to have ActiveX enabled, and the workstation has to be logged into the domain, but the iLO 2 login page will accept Both the "john@domain" and "domain\john" forms in addition to the CN or fully qualified DN.
There's an HP whitepaper, "Configuring HP integrated Lights Out With Active Directory" that has all the details you need.
Check to make sure that username you are logging in with is the CN Attribute of the account in AD. The CN is usually the name that is displayed in AD Users and Computers for a username in the panel.
One of the quirks of AD & iLO is that it uses the CN Attribute as the username identifier rather than something that is less likely to change like the SAMAccountName attribute.
