Sometimes we run into situations where we might might have to reset or change the tableau server administrator account. Here are the helpful commands to do that.
In order to run these commands, you will need access on to server where Tableau server is running.
Step 1) Clear the existing admin user with the help of ''tsm reset''
Step 2) To create admin user ''tabcmd initialuser''
ex : tabcmd initialuser --username "admin" --password "password" --server http://localhost
Hope it helps.
