Unable to pass authentication

Hello, I tried to log in using gokrb5v8 and it failed. Exception information:
KDC_Error: AS Exchange Error: kerberos error response from KDC: KRB Error: (6) KDC_ERR_C_PRINCIPAL_UNKNOWN Client not found in Kerberos database - CLIENT_NOT_FOUND

TestCode:

package main

import (
	"github.com/jcmturner/gokrb5/v8/client"
	"github.com/jcmturner/gokrb5/v8/config"
	"github.com/jcmturner/gokrb5/v8/keytab"
)

func main() {
	krbConf, err := config.Load("security_krb5.conf")
	if err != nil {
		panic(err)
	}

	keytabFile, err := keytab.Load("security_venus.keytab")
	if err != nil {
		panic(err)
	}
	krbclient := client.NewWithKeytab("venus@HADOOP.QIYI.COM", "HADOOP.QIYI.COM", keytabFile, krbConf)
	err = krbclient.Login()
	if err != nil {
		panic(err)
	}
}

I can successfully log in to the configuration files involved in the code in Java language.
I found in the debugger that the ReqBody of gokrb5 is not parsed the same as Java. I am not sure if it is because of this reason.

Diff the ReqBody of the two tools, Krb5 has several fields that are displayed differently.

You can try username without realm.

krbclient := client.NewWithKeytab("venus", "HADOOP.QIYI.COM", keytabFile, krbConf)
