We strongly recommend using your own Azure AD / O365 to manage your Frends users.
The following steps explain how to get started
Register Azure AD Application
You can use the following instructions to register a new Azure AD Application.
The Application should be a Web Application and the Sign-On URL should be the link to your Frends tenant, for example https://demo.frendsapp.com
Please make sure that the Implicit Grant - ID Tokens is enabled in the Authentication section:
Configure Frends
For Frends to be able to use the AD Application the following information is needed from the registered Application:
Application ID: e.g. 50549e93-99dd-4690-9948-3c8ec076ddfb
Tenant: e.g companyname.onmicrosoft.com (Check Azure domain address for example in https://portal.azure.com/#settings/directory)
Navigate to Administration -> User Management -> OpenId Connect Applications
