Do you know how Paradox normally authenticates people using password protected tabes? There must be a method to connect to a paradox table providing a password. If you're not using PHP how would you normally do it?
In Delphi and Borland C++ we use TSession's AddPassword(AnsiString PWORD). I've checked all of the odbc functions available in php, the only way to supply the password is using odbc_connect(DATASOURCE, UNAME, PWORD) but this doesn't seem to work.
