[Samba] smbd in hybrid mode

[Weiser, Johann]

There is this really fancy sentence in the smb.conf man page: "It is
possible to use smbd in a hybrid mode where it is offers both user and
share level security under different NetBIOS aliases." 
 
There are a number of question here in this mailing list around this
sentence and the answers are usually to use "map to guest" parameter.
However this parameter does not work e.g. with "SECURITY = server". 

Therefore I would be really interested in a solution as described with
this sentence above with different NetBIOS aliases. Does such a solution
really exist, or should this sentence be removed from the man page?
