[Samba] home directory share definition for AD integration

[Tim Allingham]

I've currently got an installation of Samba 3.4.0 with AD integration in
place, its all working correctly except for 1 case, the [homes] share.

currently the share is defined as
[homes]
        comment = Home Directories
        valid users = %S @CATS+Domain\ Admins @CATS+hazelmereusers
        read only = No
        browseable = Yes

The share shows up in the network browser fine when navigating to 

\\<serverip>
