OGRVRTDataSource and password

[Piero Cavalieri]

Hi all,
I use VRT datasource to connect to a MSSQL Server.
If password is set wrong I have output from MapServer:

...Unable to initialize ODBC connection to DSN for **/****@Archimp_STAGE...

Where **/**** are userID/wrongPasswd. i suppose if there is somelse problem
in OGRVRTDataSource settings, correct user/password are send to web page.

How can I suppress errors ?

Thanks
   Piero
