Dave, its still not clear...

how does the password transmitted over the network. Does it go encrypted one or clear text?

I recently have found some info from the Teradata ODBC driver manuals and it seems that the logon credentials get transferred as clear text to the server for validation.

Following is the extract :

Default = Cleared

When this check box is cleared, the user is enabled to connect to the database through Single Sign On (SSO), using one of the authentication mechanisms that support SSO.

In SSO, the username and password are not submitted. The Teradata Database username is derived from the user identity on the client platform.

When this check box is selected, SSO is unavailable, Conventional Sign On (CSO) is used.

In CSO from a network client, the user must provide a Teradata Database username and password. These are sent in nonencrypted clear text for validation.

Thanks & Regards,

Meenakshi Swami
