This is a strange situation but definitely a big problem for me.
My personal credentials work just fine with the Tableau Publish to Server tool.
I need to use the service account credentials which we use with tabcmd to publish Tableau datasources. This is the same service account running the Tableau Server. It is a Tableau Server Admin with full permissions.
I can use the service account credentials to set up the tool connection, then see the list of projects and datasources and such in step 2 of the tool's configuration.
But when I run the configured tool, this happens: ☹️
Publish to Tableau Server (123) Tool #33: Tool #4: Tableau Server API Request (Sign-in) Error Code 401001: Signin Error -- Error signing in to Tableau Server
I have a hunch the problem is special characters in the service account name (.) or the password (+=@). What do you think?
