Azure Logic Apps Standard/ Azure Function integration with on-premise active directory

I am working on migrating the BizTalk solution to Azure Logic App Standard. One of BizTalk application receive messages from HR system and connect to active directory using Active Directory adaptor ( which use LDAP). Application create new user, updated existing user attributes and disable user in AD.
We use AD Connect to sync the Azure Active Directory, but we can create new user or update existing user in Azure AD due to current implementation and security design.
I am looking for option to do same using Azure Logic app Standard or Azure Functions. What are the option to connect to on-premise active directory to create and update existing user?
