3 months ago Well why is the server responding 401? The library worked as intended. You got a ticket to use.

I'm currently working on generating a Kerberos ticket using the Kerberos.Net NuGet package. My objective is to use this ticket to authenticate and access a third-party API. However, despite my efforts, I am encountering a 401 Unauthorized error.
string keyTabFilePath = "myPath" var krb5Config = new Krb5Config(); // settings some kdc configurations.
using(var client = new KerberosClient(krb5Config)) { var keytab= new KeyTable(File.ReadAllBytes(keyTabFilePath)); var kerbCred = new KeytabCredential("myUser.corp", keytab);
await client.Authenticate(kerbCred); var ticket = await client.GetServiceTicket("zzz/x.corp"); var token = Convert.ToBase64String(ticket.EncodingGssApi().ToArray());
HttpClientHandler handler = new HttpClientHandler() { UseDefaultCredentials = false } using(HttpClient client = new HttpClient(handler)) { client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Negotiate", token); HttpResponseMessage response = client.GetAsync(apiUrl).Result; }
}
I'm using this code to generate a Kerberos ticket and authenticate to access a third-party API. The expected outcome is to receive a 200 HTTP status code, indicating a successful request. However, I'm currently receiving a 401 Unauthorized error.
I'm sure I'm missing something. Thank you in advance for your help.
Best regards,
