it seems that when a configuration is defined at design time as integrated
security there is no simple way to change that setting using configs at run
time.

You can add username and password values, but when the connection string is
rebuilt, the "Integrated Security=SSPI;" parm is left over and the userid/pwd
are ignored.

there is no apparent way to remove the "Integrated Security=SSPI;" clause
using configured properties.

Does one have to resort to configuring the entire connection string? Then
this is rebuilt and lost if any other property of the connection is defined
elsewhere.

Please advise.

Hi Dwain,
Welcome to Microsoft MSDN Managed Newsgroup.

If you want to override the connection settings in your package at design
time, you can use the option /Connection. Please refer to this article:

Hope this helps.
