问题
BackGround : User once logged in to the our Web Application (using App level credential) will be presented with with Mail System they want to use based on that user will be redirected to respective authorization server to authenticate (using login / password of their mail system) and the auth server will return an access token back.
In Notification events like OnAuthorizationCodeReceivedAsync or OnAuthenticationFailedAsync; we are not getting ASP.NET_SessionId so having said that i am not able to use any of the session values which are set before OAuth Flow.
Refer below Code for more details.
app.UseOpenIdConnectAuthentication(New OpenIdConnectAuthenticationOptions With {
.ClientId = appId,
.ClientSecret = appSecret,
.Authority = "https://login.microsoftonline.com/common/v2.0",
.Scope = $"openid email profile offline_access {ewsScopes}",
.RedirectUri = redirectUri,
.PostLogoutRedirectUri = redirectUri,
.TokenValidationParameters = New TokenValidationParameters With {
.ValidateIssuer = False
},
.Notifications = New OpenIdConnectAuthenticationNotifications With {
.AuthenticationFailed = AddressOf OnAuthenticationFailedAsync,
.AuthorizationCodeReceived = AddressOf OnAuthorizationCodeReceivedAsync
}
})
I am not able to get any session values in HttpConext.Current.Session which are set before OAuth flow in notification events.
As per below SO; i tried different approaches like SystemWebCookieManager, UseKentorOwinCookieSaver but issue not resolved.
ASP.NET_SessionId + OWIN Cookies do not send to browser
What could be the issue and how can I resolve it?
