Encryption of credentials transmitted between client and Teradata database

Hi,

We plan to use the Microsoft Connector for Teradata by Attunity 3.0 - 32 -bit to connect using LDAP authenticaqtion from a SSIS package to a Teradata database.

Is there an option to transmit the credentials in an encrypted form? if so how can that option be switched on and what encryption mechanism is used?

Thanks
Harsha
