Azure AD DS ldap integration

Hello Support,

I am trying to figure out if Azure AD DS can allow custom written applications to authenticate end users, using their Office 365 credentials. The application requires LDAP to authenticate, and I was under the impression that Azure AD DS can do this... I am looking for any help or documentation that will show me how to provide the application a access url or uri that will be integrated into the code, to check with Azure AD DS and authenticate the end user with their O365 user name and password, via LDAP or SLDAP

Thank you and Best regards,

Jason C

@JasonC-7274, You can get your custom written application working on legacy auth protocols like Kerberos and NTLM to work with Azure AD DS. Azure AD DS also supports LDAP and LDAPS. Ideally all the users who are present in the Azure AD, would be synced to the Azure AD DS's directory.

[Note: In case of hybrid scenario, the Password Hash Sync has to be enabled, so that password hash from on-prem can get synced to cloud and from there get synced to Azure AD DS]

Once you enable the Azure AD DS service in your tenant, a dedicated VNET gets created that is connected to the Domain Controllers that gets created in the backend. Now you can go ahead and create a VM and connect that VM to the same VNET and get that VM domain joined to the Azure AD DS domain. Once done with the domain join you can install the RSAT tools on that Windows VM and manage the functionalities of the Domain Controller. Also, you can domain join Webserver hosting your custom app on IIS and get them authenticated with Azure AD DS Domain Controllers.

You can get more information on Azure AD DS, by referring to the links below:
