It would be nice to have both LDAP and Local Accounts within Storage Manager. This way you can have users with AD privs have access to do things they should be able to, and still have a generic quick login for ReadOnly type accounts where it doesn't matter who has it, and has a simple password (most companies these days have AD password requirements for security reasons that are painful for a quick account for a team to use)
Its possible also in some environments I bet where some people might not have AD accounts and some might.
