The only issue here was due to dependency issues downgrading to samba 3.5.4 resulted in libwbclient0 being downgraded which resulted in the removal of ubuntu-desktop.

Hi, samba 3.6.3 on Ubuntu 12.04 using winbind does not show domain 
groups using 'getent group'  but 'getent group <domain group> will, 
provided that the domain group has the posix objectclass 'posixGroup' 
and a gidNumber. If all is correct, it will work, try creating a file 
and chown <domainuser>:<domaingroup> it
