I wonder if your problems are being caused by the use of the smbpasswd 
passdb ?

If you examine 'man smb.conf' for 3.6, you will find this (under 'passdb 
backend') :

            • smbpasswd - The old plaintext passdb backend. Some Samba
                features will not work if this passdb backend is used.

Perhaps if you migrate to tdbsam it will work, not sure because I have 
never had to do it, but it is worth trying in a test setup, I believe 
that you can do this with pdbedit.
