I see the problem now. On your Win32 box, the ODBC driver lets you specify the server's database filename. How to do that with FreeTDS?
AFAIK, the server_name field of the login packet is the only place to pass the database name to the server. That field is limited to 30 characters. A quick scan of src/tds/config.c leads me to suggest that:
host = myserver.company.com
port = 2638
tds version = 5.0
dump file = /tmp/tdsdump.txt
might work. Obviously you'll need to quote such a name when you provide it to tsql. You can't use ':' in the name because the config file reader trips on it. But if database file is on the server's default drive, you can use a relative pathname, yes?
That particular name is 27 characters. If there's a way to pass longer names to the server (or, if that way doesn't work), I'd like to know what it is. We'd need a wire trace to see what they're doing; "windump -s 1500 -w ODBC.trace host <hostname> and port <port> and tcp" would do fine.
If that doesn't work (and your path <= 30 characters), please check the TDSDUMP log to make sure we're passing it correctly. If we're not, post it here and we'll correct it. Else we'll definitely need a trace.
