Integration of legacy authentication with cloud-based authentication

A method, comprising:

• requesting authentication to access an on-premise application from a cloud computing service using a cloud-based authentication protocol, wherein the on-premise application adheres to a legacy authentication protocol, the cloud-based authentication protocol adheres to a cloud-based authentication protocol, the legacy authentication protocol differs from the cloud-based authentication protocol;
• receiving a security token including a security ticket of the legacy network authentication protocol, the security ticket generated by an identity provider of the cloud computing service, the security token associated with the cloud-based network authentication protocol;
• transmitting an authentication request using the legacy network authentication protocol to the on-premise application, the authentication request including the security ticket;
• and
• obtaining access to the on-premise application.

A device, comprising:

• at least one processor and a memory;
• wherein the at least one processor is configured to:
• receive an authentication request, at a cloud computing service, for access to an on-premise application, the authentication request associated with a cloud-based authentication protocol from a client application, the on-premise application associated with a legacy authentication protocol, the cloud-based authentication protocol differs from the legacy authentication protocol;
• upon successful verification of the authentication request, generate an authentication token of the cloud-based authentication protocol having an authentication ticket of the legacy authentication protocol;
• and
• provide the authentication token to the client application to authenticate to the on-premise application through the legacy authentication protocol using the authentication ticket.
