Currently, if you want to change from Built-in to Windows Authentication, you have to:
To switch authentication types, you'll need to start from scratch.
1. Stop the AlteryxService
2. Open a Windows Folder Explorer and go to the directory you have MongoDB loaded (System Settings->Controller->Persistence->Data Folder
3. Rename or delete that folder (a simple backup would be to rename the folder, you can move it to another directory as well)
4. Open the Alteryx Server System Settings and click next to Gallery->General.
5. Select the new Authentication process you would like to use.
6. Finish the System Settings and the new database will be created.
The Gallery and Scheduler databases are closely tied. Workflows that are uploaded, results created, and schedules created from the Gallery are stored in the Scheduler database. So you will need to start from scratch on both the Gallery and in the Scheduler.
This is a non-starter for any company that has any amount of time invested in establishing the use of the Gallery. Starting over is not an option, but improving security, streamlining access protocols as a part of overall data governance is a must. Please consider fixing the authentication protocol to make it so we don't have to start over.
Thank you,
