30 Enroll a user on a credential provider.
32 This function enrolls a user on this credential provider. If the user exists on this credential
33 provider, update the user information on this credential provider; otherwise add the user information
34 on credential provider.

37 @param[in] User The user profile to enroll.
39 @retval EFI_SUCCESS User profile was successfully enrolled.
40 @retval EFI_ACCESS_DENIED Current user profile does not permit enrollment on the user profile
41 handle. Either the user profile cannot enroll on any user profile or
42 cannot enroll on a user profile other than the current user profile.
43 @retval EFI_UNSUPPORTED This credential provider does not support enrollment in the pre-OS.

136 Return the user identifier associated with the currently authenticated user.
138 This function returns the user identifier of the user authenticated by this credential provider. This
139 function is called after the credential-related information has been submitted on a form OR after a
140 call to Default() has returned that this credential is ready to log on.
142 @param[in] This Points to this instance of the EFI_USER_CREDENTIAL2_PROTOCOL.

164 Indicate that user interface interaction has begun for the specified credential.
166 This function is called when a credential provider is selected by the user. If AutoLogon returns
167 FALSE, then the user interface will be constructed by the User Identity Manager.

225 information. If the buffer is too small to hold the information, then
226 EFI_BUFFER_TOO_SMALL is returned and InfoSize is updated to contain the
227 number of bytes actually required.
