[Samba] [samba4 dc ldap] LDAP_SERVER_FAST_BIND_OID is currently not supported?

[Tide]

I'm testing LDAP authentication against samba4 using fast bind connection
control. I got the following java exception
----------------------------------------
javax.naming.NamingException: [LDAP: error code 1 - Operations Error]
----------------------------------------

and got error message from samba
----------------------------------------
ldapsrv_do_call: Critical extension 1.2.840.113556.1.4.1781 is not known to
this server
----------------------------------------

Is fast bind control not yet supported? Any plan to support it?
