What code did you use to set the login hint?

[saurabhsathe-ms]

@jmprieur I did not use any tool. Postman is what I usually used to use. But Postman is blocked. Hence just using simple get query. Here is something that I used: https://localhost:5001/MicrosoftIdentity/Account/SignIn?redirectUri=/&[email protected]&domainHint=msidlab4.onmicrosoft.com
