1. Create a new FreeRadius Virtual site for Supermicro IPMI (without enabling SQL support)

FreeRadius With SQL

1. Edit /usr/local/etc/raddb/dictionary and add a new attribute
   ATTRIBUTE IPMI-radius  26 octets
   3. Edit /usr/local/etc/raddb/policy.d/foo and add
   foo {
        update reply {
          # Vendor-Specific = "H=4"
          &Attr-26 = 0x483D34
        }
   }
   0x483D34 is Hex Code for String "H=4"

If you need other type of permission (e.g. H=3) just change the string to hex code.

1. Edit /usr/local/etc/raddb/users and add the following user
   ipmiAdmin Cleartext-Password := "Any-password"
             IPMI-radius += "0x483d34"
   You can replace ipmiAdmin and authorization type.

1. Restart FreeRadius

1. Login to Supermicro IPMI and enable Radius support.
