根据https://www.pgadmin.org/docs/pgadmin4/development/kerberos.html ，我正在尝试将 pgadmin4 容器映像与 kerberos 一起使用。
pgadmin 网络界面不断告诉我“未提供委托凭据”。但是 Authorization 标头传输正确。我在做什么错`？
这是一个卷曲转储：
命令行：
kinit myuser
curl -v --negotiate --user : http://***MYHOST***/login
输出：

编辑： 请理解我隐藏了主机、用户和领域来伪装我的雇主。
来自容器内部的更多详细信息：
/pgadmin4 # klist -k -t /etc/krb5.keytab
Keytab name: FILE:/etc/krb5.keytab
KVNO Timestamp Principal
---- ----------------- --------------------------------------------------------
3 01/01/70 00:00:00 HTTP/***MYHOST***@***MYREALM***
/pgadmin4 # kinit ***MYUSER***
Password for ***MYUSER***@***MYREALM***: ***
/pgadmin4 #
...所以我得出结论我的 keytab 是正确的，我的 kerberos 配置有效（由于 kinit 有效）（？）
顺便说一句，我在同一主机上使用具有相同 serviceprincipalname 的相同 keytab 和一个可以工作的 webserver 容器 - 所以我一般不怀疑 serviceprincipalname 有问题（？）
