遇到一個很棘手的問題，求大神支招，雪地跪求，萬分感謝。
我用C#寫了一程式需要訪問資料，當時C#程式跑在window下，可以正常訪問windows服務器上的Sqlserver。但將程式部署到Linux服務器上之后，訪問windows服務器上的SQLServer 報如下錯誤：
Cannot authenticate using Kerberos. Ensure Kerberos has been initialized on the client with 'kinit' and a Service Principal Name has been registered for the SQL Server to allow Kerberos authentication.

針對此錯誤我主要做了以下兩點，但還是沒有解決此問題：
1，參考此貼 https://github.com/dotnet/corefx/issues/22184，我做了如下幾點：
（1）將Trusted_Connection=true 改成 Trusted_Connection=false,結果還是不行，但報的錯誤發生了變化，此時報如下錯誤：
System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'UserName\Password'.
at System.Data.SqlClient.SqlInternalConnectionTds..ctor(DbConnectionPoolIdentity identity, SqlConnectionString connectionOptions, SqlCredential credential, Object providerInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString userConnectionOptions, SessionData reconnectSessionData, Boolean applyTransientFaultHandling, String accessToken)

at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest(DbConnection owningObject, DbConnectionOptions userOptions, DbConnectionInternal oldConnection)
at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, UInt32 waitForMultipleObjectsTimeout, Boolean allowCreate, Boolean onlyOneCheckConnection, DbConnectionOptions userOptions, DbConnectionInternal& connection)
at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, TaskCompletionSource`1 retry, DbConnectionOptions userOptions, DbConnectionInternal& connection)
at System.Data.ProviderBase.DbConnectionFactory.TryGetConnection(DbConnection owningConnection, TaskCompletionSource`1 retry, DbConnectionOptions userOptions, DbConnectionInternal oldConnection, DbConnectionInternal& connection)
at System.Data.ProviderBase.DbConnectionInternal.TryOpenConnectionInternal(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource`1 retry, DbConnectionOptions userOptions)
at System.Data.SqlClient.SqlConnection.TryOpen(TaskCompletionSource`1 retry)
at System.Data.SqlClient.SqlConnection.Open()
（2）將Trusted_Connection=true 改成 Trusted_Connection=no,結果同上。
（3）將Trusted_Connection=true 洗掉,結果同上。
2,我將windows服務器和linux 服務器加入到同一個域中（公司的域），但還是報 Cannot authenticate using Kerberos .
在此感謝大神們的支招！！
uj5u.com熱心網友回復：
這個應該是Windows版本支持K鑒權機制，這個應該是可以選擇另一種機制的轉載請註明出處，本文鏈接：https://www.uj5u.com/caozuo/90485.html
