It is described in the smb.conf manpage, but briefly if you try to 
connect to a share called 'username' and samba knows nothing about a 
share called 'username' it checks if there is a user called 'username'. 
If this user exists, it obtains the users Unix homedir and uses this for 
the share name and path. So if there is a user called 'username' and 
there is a share called '[homes]' in smb.conf, then the users homedir is 
obtained, on a DC this will be '/home/DOMAIN/username' unless 'template 
homedir = ' is set to in smb.conf, on a domain member, winbind will use 
the contents of the 'unixHomeDirectory' attribute, but this *must* be a 
local path.

Profiles have *nothing* to do with home directories.

If you are trying to connect from windows using the profile share, you 
will need to use [profiles] not [homes] or [home], not sure if this will 
work, because the profile (as far as I am aware) is written at first 
logoff and then updated at each subsequent logoff.

Nope, all recent versions of Samba have worked in this way.
