Hi,
I don't know the exact combination but I don't see any reasons why this
should
not work.
>From Windows the default and best option is to use SSPI which will provide
the authentication options that best suit the system.
>From Linux you can use either NTLMv2 or Kerberos. For NTLMv2 you have to
provide username/password as Linux does not store AD authentication, for
Kerberos you have to have a ticket ready.
Maybe you need to specify some options like "use ntlmv2" (see
http://www.freetds.org/userguide/freetdsconf.htm).
Empty username and password are used for Kerberos authentication.
