Get users from LDAP and authenticate in SharePoint Online

Question

I have a SharePoint Online site, where users are in LDAP but not in SharePoint. How to get users from LDAP and connect to SharePoint Online site. I appreciate if any one have any ideas on this and it would be great help if you know what can be done for authorisation after authentication through LDAP.

Thanks, Santosh

Answer 1

See: https://support.office.com/en-us/article/Office-365-integration-with-on-premises-environments-263faf8d-aa21-428b-aed3-2021837a4b65 for a more thorough description of what I've tried to describe here.

Option 1 - Use Azure Active Directory Connect to sync your on-premise ADFS with Office 365 ADFS

You will need to set up a synchronization between your on-premise ADFS with the Azure ADFS that exists on Office 365.

• Before you sync, you need to set up your active directory such that it is compatible to be synced with an Azure Active Directory: https://support.office.com/en-us/article/Prepare-to-provision-users-through-directory-synchronization-to-Office-365-01920974-9e6f-4331-a370-13aea4e82b3e?ui=en-US&rs=en-US&ad=US
• There is also a tool called IdFix that will identify problems that you have on your on-premise ADFS that will cause issues once you try to sync to the Azure ADFS https://support.office.com/en-us/article/Install-and-run-the-Office-365-IdFix-tool-f4bd2439-3e41-4169-99f6-3fabdfa326ac?ui=en-US&rs=en-US&ad=US
• Set up AD Synchronization for Office 365: https://support.office.com/en-us/article/Set-up-directory-synchronization-for-Office-365-1b3b5318-6977-42ed-b5c7-96fa74b08846
• Install Azure Active Directory Connect: https://docs.microsoft.com/en-us/azure/active-directory/connect/active-directory-aadconnect

Option 2 - Use a third party tool

You can also use a tool called Okta which I have not used but it sounds like it does a lot of the leg work for you: https://www.okta.com/office365/
