OK, lets take these one by one, you seem to have a problem with the 
ridmaster fsmo role, what does this return:

ldbsearch -H /var/lib/samba/private/sam.ldb -b 
'CN=System,DC=cb,DC=cliffbells,DC=com' -s sub 
'(&(objectclass=rIDManager)(cn=RID Manager$))' fSMORoleOwner

On my system:

# record 1
dn: CN=RID Manager$,CN=System,DC=samdom,DC=example,DC=com
fSMORoleOwner: CN=NTDS 
Settings,CN=DC1,CN=Servers,CN=Default-First-Site-Name,C
  N=Sites,CN=Configuration,DC=samdom,DC=example,DC=com
