[CentOS] MegaRAID Storage Manager on CentOS 5.5?

Does anyone have the 'MegaRAID Storage Manager' GUI working on CentOS 5.5?

I can run it, but it won't let me log in.

The docs state that it requires the local root username and password - 
but it always rejects this with "Message = Login failed: Invalid 
username or password!"

Thanks
