Each object has a distinguished name which determines not only the object's name itself but also the place where the object is stored in the directory hierarchy. These distinguished names are specified in RFC 4514 and you can find a good description on LDAP distinguished names in the SelfADSI tutorial. In some directory environments, the distinguished name are handled not in the pure LDAP way, but with a slightly different notation. Primarily in Novell eDirectory environments the dotted notation is widely used. So you can switch to this output if you want.
Example for an LDAP distinguished name:

But please note that you see the dotted Novell notation only if you disable the friendly name output for the distinguished names. But if you display full distinguished names and activate the output in Novell notation, this is also applied to the attribute list:
