我正在使用带有 unixODBC 的 Freetds 从 linux 连接到远程 SQL 服务器实例。linux 服务器集成了 AD，我使用域登录 ssh 进入服务器。
但是 TDS（7.1 版）无法连接并失败并显示错误消息
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Error 20002 (severity 9):
Adaptive Server connection failed
There was a problem connecting to the server
设置 TDS Dump 变量，我运行了命令
tsql -H server.domain.local -p 52890
使用非标准端口，因为我连接到在 1433 以外的端口上运行的命名实例
下面是调试日志
net.c:1370:handshake succeeded!!
gssapi.c:215:kerberos name MSSQLSvc/<server Name>
login.c:466:login packet rejected
util.c:156:Changed query state from IDLE to DEAD
util.c:331:tdserror(0x2139160, 0x2139400, 20002, 0)
util.c:361:tdserror: client library returned TDS_INT_CANCEL(2)
util.c:384:tdserror: returning TDS_INT_CANCEL(2)
我能够连接到启用了 SQL Server 身份验证的另一台服务器，因此 ODBC 连接本身没有问题。此特定服务器仅启用了域身份验证，因此我无法检查 SQL Server 身份验证是否正常工作。

使用 KRB5_TRACE 变量添加了 Kerberos 跟踪。很抱歉日志文件太长
