samba - Feb 2013 - Samba4 - Shared folder not showing security tab in windows explorer

I am able to join Windows 7 work station to domain. I logged in as domain
administrator in windows work station for testing. I am able to see netlogon,
sysvol and the homes shared folders in the windows explorer in the client.
However, I am not getting security tab when I right click on homes share and
choose properties. Security tab is available when I right click and choose
properties on netlogon and sysvol share. Security tab is missing only for the
share I added in smb.conf. I tried changing the permissions on the /sambahome
directory I have shared (please see ls -al /sambahome below). Spent whole day
googling and trying various things. No luck so far. Highly appreciate any hint,
help and guidance. Thanks for your time :-) Environment: Samba 4.0.3 compiled
