Switch from Azure Active Directory/Google authentication to custom login

If a user is using AAD/Google Login but you want to switch it to custom login with a SIGNL4 account, you need to dp the following steps:

1. Delete the user from your subscription
2. Re-invite the user
3. Once the user receives the invitation email and confirms, he/she needs to choose the proper logon method on the sign-in webpage. For custom login he/she just needs to put the login name and the password to login with a SIGNL4 account
