[Mono-list] asp.net conversion advice needed.

Each Access form is converted into a separate asp page.  In each page there
are options to either declare
a connection string there or use the one from web.config.  We went into each
page and made sure it's trying to use 'ConnectionString' from the web.config
file.  This works in windows with a connection string that contains
'Driver="MySql ODBC 5.1 Driver" but when you move that web.config file to
the linux box the connector/net driver that was installed there isn't called
the same thing.  On Suse all we knew to do was install the connector/net
driver according to the mono page where it talks about adding it to the GAC. 
Since it can't find a driver called 'MySQl ODBC 5.1 Driver" it seems to be
defaulting to standard odbc drivers which are not set up at all.  Honestly I
don't even know how to setup the dsn on suse using mysql.  It won't be a
problem to debug this on the server.  Right now it's just a test box

I'm not at work so I can't get a copy of the web.config right now. 
Hopefully tomorrow I'll be back in the office.
