TL;DR: Having trouble identifying the correct server, username, and password combination to connect MySQL to an existing MSSQL database using Windows Authentication. Will I need to create a separate user for the migration, or is it possible to connect to MySQL in the Migration Wizard using MSSQL Windows Authentication?
Background and Debugging Steps
I received a BAK file which I would like to import into my existing MySQL installation. I have successfully imported the BAK file into Microsoft SQL Server Management Studio 18 (MSSQL). I am now trying to migrate the database to MySQL using the Database Migration Wizard in MySQL Workbench 8.0.27.
I believe the issue I am running into relates to authentication. In MSSQL I am connecting to the server using Windows Authentication. My User name is "AzureAD\ZachLonghofer" and MSSQL takes care of the password. In the MySQL migration wizard, using the default connection method, I receive this message log:

I also tried using ODBC (native) and specifying the Server: ZLONGHOFER\SQLEXPRESS01 -- which is what shows as the server in MSSQL. With this configuration, I receive this message log, which is identical until after the traceback:

Windows Authentication
The password I am using is my windows user password. I'm fairly certain I've never set a password for MSSQL: I've only ever used Windows Authentication and I thought the username and password would parallel my Windows Login and Password, but it seems not.
It also occurs to me that I may need to create a user in MSSQL if it may not be possible to import to MySQL using Windows Authentication connection to MSSQL. If so, I will need to [figure out how to] create a separate user in MSSQL to do the migration.
Will I need to create a separate user for the migration, or is it possible to connect to MySQL in the Migration Wizard using MSSQL Windows Authentication?
TL;DR;
When you log in on a Windows machine you use Windows Authentication. The user logged in is the same one used by the SSMS, this one doesn't take care of your password simply because it doesn't need you are already authenticated to Windows, and this "mechanism" is the same for every program you use.
Your question omitted the most important "piece": the connection string or at least the code/library you use to connect to MsSQL Server.
Microsoft SQL Server (on premises) can run in two mode:
Integrated authentication only
Mixed mode -> Integrated authentication AND Sql Server authentication
On mode 1 you can only login to SQL Server using Windows Authentication only whenever on mode 1 you can use Windows Auth and users created directly on SQL Server.
From the log I see
Opening ODBC connection to DRIVER={SQL Server};SERVER=ZLONGHOFER\SQLEXPRESS01;DATABASE={};UID=AzureAD\ZachLonghofer;PWD=XXXX;
UID and PWD are symptoms using a Sql Server Authentication NOT Windows Authentication.
TODO
If you want to use Windows Authentication you must remove user and password from your connection string and add Integrated Security=true; this specify to use the Win Auth see here for connection strings
If you want to use a SQL Server User, you must create a user and assign at least the reader of the DB and then use the username and password, here a tutorial on how to
I have an AWS Lightsail instance running the Bitnami configuration for Ubuntu 16.04.5 LTS and PHP7.
I can connect the the MySQL database using phpMyAdmin on the server via an SSH Tunnel. But when I try to configure DataGrip for SSH access to the database I receive the error message "Host '127.0.0.1' is not allowed to connect to this MySQL server".
When I remove "localhost" from the host field of the General tab then I receive the error "ExecutionException: SSH: Unable to find host/port in URL".
The following test and response appears to show a successful connection to the port:
cat < /dev/tcp/###.###.###.###/22
SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.6
I'm using keypair auth. Both the user name and the Private key file are the same used for the ssh tunnel when running phpMyAdmin.
Not sure what to try next. Any help appreciated.
I have an Tomcat 7 application on openshift and I have added a MySQL cartridge. I have a problem connecting to that database using MySQL workbench.
I have added all the necessary parameters like hostname, username, password and SSH key, I have tested the connection and I get no errors. But when I try to connect to the db I get the following error:
Your connection attempt failed for user 'adminxxxx' from your host to server xx.xxx.xxx.xxx:3306:
Tunnel error: Remote connection to xx.xxx.xxx.xxx:3306 failed: IOError('open SSH tunnel timeout',)
What can I do to fix this? Connecting to the db is a big part of the application.
I am trying to connect to a psql database from octave but getting a peer authentication failed error.
error: FATAL: Peer authentication failed for user
error: PQ connection attempt failed
check your pg_hba.conf file I think in that file there is no entry of your current user.

I have a MySQL database I'm able to connect via the command prompt and the MySQL administration tool but using the same credentials in a Web application in a Tomcat server on the same server gives me this error:
javax.servlet.ServletException: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Could not create connection to database server. Attempted reconnect 3 times. Giving up.)
Which I recognize as an incorrect credentials issue. I checked that the MySQL server is listening on port 3306 using netstat. I don't have the mysql root credentials but I created a new account and granted all priviledges to it and are the ones used to connect both using the command prompt and the MySQL admin tool.
Turned out to be a caching issue. Disabled the context caching in the web application in order to "see" the changes. Windows doesn't show this behavior/issue.
