Unable To Log In With Basic Authentication After A Server Migration Or Site Hardening

Why are users not able to log into Orchestrator using a local user profile, such as an admin account?

Issue Description:

After a server migration or site hardening exercise, an admin or user may find that they are no longer able to log into an on-premise Orchestrator instance local account using basic authentication, which had been enabled previously.

In checking Host settings, while some method of SSO may be enabled, there may be no indication that basic authentication has been restricted, or the RestrictBasicAuthentication parameter has been enabled in Identity\appsettings.Production.json.

Resolution:

Restoring ""EnableBasicAuthenticationApis": true," in the [Appsettings] section of Identity\appsettings.Production.json (C:\Program Files (x86)\UiPath\Orchestrator\Identity) restores the ability to login with local user credentials.
