Error, IM002:1:0:[unixODBC][Driver Manager]Data source name not found, and no default driver specified

Following steps to Enable Password Checkout for Microsoft SQL Server (MSSQL) database monitoring
Problem with unixODBC not recognizing, finding, picking-up the configured SQL driver
The following error displays after clicking "Test Connection" when configuring a new or modifying an existing Microsoft SQL Server Database Account Domain:
Error, IM002:1:0:[unixODBC][Driver Manager]Data source name not found, and no default driver specified

Please verify the following:

• The driver configuration file is named odbcinst.ini and is provided in the same path / directory / folder as odbc.ini
  
• The ODBC Initialization Path is a path / directory and not an actual path to the file (i.e. /root/odbc.ini). Please provide a directory path to where both odbcinst.ini and odbc.ini files exist.
  
• The Driver name defined in odbcinst.ini is the same as the Driver attribute defined in the datasource of odbc.ini.
  Note: If odbcinst.ini has the driver defined as “[ODBC Driver 13 for SQL Server]” then verify the odbc.ini references “Driver=ODBC Driver 13 for SQL Server”
  

This error is typically caused by a misconfiguration of the odbc.ini and odbcinst.ini files or the ODBC Initialization Path.
