How To Solve Error 28000: Login failed for user DOMAIN\user with pyodbc Error ?

  2. Error 28000: Login failed for user DOMAIN\user with pyodbc

    To Solve Error 28000: Login failed for user DOMAIN\user with pyodbc Error If you want to use “SQL Server Authentication” with a specific SQL Server login specified by UID and PWD then use Trusted_connection=no.

Solution 1

Connecting from a Windows machine:

With Microsoft’s ODBC drivers for SQL Server, Trusted_connection=yes tells the driver to use “Windows Authentication” and your script will attempt to log in to the SQL Server using the Windows credentials of the user running the scriptUID and PWD cannot be used to supply alternative Windows credentials in the connection string, so if you need to connect as some other Windows user you will need to use Windows’ RUNAS command to run the Python script as that other user..

If you want to use “SQL Server Authentication” with a specific SQL Server login specified by UID and PWD then use Trusted_connection=no.

Connecting from a non-Windows machine:

If you need to connect from a non-Windows machine and the SQL Server is configured to only use “Windows authentication” then Microsoft’s ODBC drivers for SQL Server will require you to use Kerberos. Alternatively, you can use FreeTDS ODBC, specifying UIDPWD, and DOMAIN in the connection string, provided that the SQL Server instance is configured to support the older NTLM authentication protocol.

Solution 2

I tried everything and this is what eventually worked for me:

import pyodbc
driver= '{SQL Server Native Client 11.0}'

cnxn = pyodbc.connect(
    Trusted_Connection='Yes',
    Driver='{ODBC Driver 11 for SQL Server}',
    Server='MyServer,1433',
    Database='MyDB'
)
