I have local AD and AD on azure and I have ADFS and ADFS proxy server setup to authenticate users on local AD. I have followed all the steps on microsoft site to setup trust between Azure AD and local AD. However it says Dir Sync is necessary in order to achieve SSO for users in local and cloud AD. I don't want to use Dir Sync and I want my ADFS to be able to authenticate users from my local AD and Azure AD as well.
Can anybody let me know the steps in order to achieve it.
