Hi All,
I am using Azure AD Claim based Authentication in my ASP.Net MVC project. Application was running fine for 6 months suddenly intermittently it started throwing below error
I put logs in my application and found that when request gets invalidated, then system tries to
Authentication.Challenge for redirection (Code Snippet below) to external AD login page, but login page never comes up. When I restart the IIS, it again starts working then same process after 3-4 hours same error start and it stops application
for all users.
Please provide any help on this issue
var properties = new AuthenticationProperties { RedirectUri = ApplicationRedirectUri };
if (!string.IsNullOrEmpty(userName.Trim()))
{
properties.Dictionary[XsrfKey] = userName;
}
else
{
string uid = Common.GetUIDCookie(Constants.UserID_Cookie);
if (!string.IsNullOrEmpty(uid))
properties.Dictionary[XsrfKey] = uid;
}
HttpContext.GetOwinContext()
.Authentication.Challenge(properties, OpenIdConnectAuthenticationDefaults.AuthenticationType);
