A user credential sharing mechanism which can suitably implement a single sign-on function while preventing illicit accesses by accidental matches of authentication data in a mixed environment of an environment suitable for use of a single sign-on function and an unsuitable environment is provided. To accomplish this, when an information processing apparatus of this invention receives, from a user, an access request instruction to an external apparatus connected to be able to communicate with the information processing apparatus, if an authentication protocol related to user credentials generated at the time of a login operation is that which can limit a security domain, the apparatus accesses the external apparatus using the user credentials, and if that authentication protocol is that which cannot limit a security domain, the apparatus prompts the user to input an account accessible to the external apparatus. |
