Access the Megaraid Storage Manager Utility using a domain account

Yesterday I was at a customer's site, he has IBM servers that use the MegaRAID family of adapters.
In order to manager the arrays we installed the Megaraid Storage Manager utility.
The utility requires authentication each time you try to manage a system.

And here we come to the issue: the server is a member server in an Active Directory Domain and the customer wanted to access the utility using a domain account.

We tried to use LDAP settings and everything without success.

We finally discovered that none of this is necessary.

You just need to open the Megaraid Storage Manager, click Login against the desired server,

and specify the credentials in this form:
username@yourdomain.com

BOOM! You're done!
