Check here: http://developers.de/blogs/damir_dobric/archive/2006/07/31/890.aspx and http://msdn.microsoft.com/en-us/library/ff648505.aspx

Transport seems to require HTTPS to encrypt credentials and throws an exception if there is no SSL. TransportCredentialOnly will send the credentials in plain text and unencrypted and is recommended for testing ONLY!

Good Luck!!

With TransportCredentialOnly security mode, the underlying secure transport layer (usually TLS/SSL) provides the integrity and confidentiality protection for the communication, while SOAP messaging layer handles transporting the client credentials in the SOAP message.

In other words, TransportCredentialOnly security mode passes the user credentials in the SOAP message without encrypting or signing the SOAP message, and the underlying transport connection (typically TLS/SSL) needs to ensure that the message contents cannot be seen or altered by a third-party.
