unixODBC driver manager search behavior for configuration files

The default behavior of the unixODBC driver manager is to search certain places in sequence to locate the two ODBC configuration files.

The unixODBC driver manager searches for the files as follows:
  1. The driver manager first searches the home directory of the current user for the .odbcinst.ini and .odbc.ini hidden configuration files. If the two configuration files exist as non-hidden files in the home directory of the user, the driver manager ignores them.
  2. If the driver manager does not find hidden configuration files in the home directory of the user, it next searches the /usr/local/etc directory for the odbcinst.ini and odbc.ini non-hidden configuration files. If the two configuration files exist as hidden files in the /usr/local/etc directory, the driver manager ignores them.
