asp.net - Sql异常用户登录失败

我有一个应用程序和一个WCF服务，它是该应用程序的一部分。如果我直接调用该服务会发生以下异常：

“System.Web.Services.Protocols.SoapException：Server无法处理请求.---＆gt; System.Data.SqlClient.SqlException：用户'Kanix'登录失败。\ u000a在System.Data.SqlClient .SqlInternalConnection.OnError（SqlException异常，Boolean breakConnection，Action 1 wrapCloseInAction)\u000a at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose)\u000a at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady)\u000a at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)\u000a at System.Data.SqlClient.SqlInternalConnectionTds.CompleteLogin(Boolean enlistOK)\u000a at System.Data.SqlClient.SqlInternalConnectionTds.AttemptOneLogin(ServerInfo serverInfo, String newPassword, SecureString newSecurePassword, Boolean ignoreSniOpenTimeout, TimeoutTimer timeout, Boolean withFailover)\u000a at System.Data.SqlClient.SqlInternalConnectionTds.LoginNoFailover(ServerInfo serverInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString connectionOptions, SqlCredential credential, TimeoutTimer timeout)\u000a at System.Data.SqlClient.SqlInternalConnectionTds.OpenLoginEnlist(TimeoutTimer timeout, SqlConnectionString connectionOptions, SqlCredential credential, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance)\u000a at System.Data.SqlClient.SqlInternalConnectionTds..ctor(DbConnectionPoolIdentity identity, SqlConnectionString connectionOptions, SqlCredential credential, Object providerInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString userConnectionOptions, SessionData reconnectSessionData)\u000a at System.Data.SqlClient.SqlConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningConnection, DbConnectionOptions userOptions)\u000a at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnectionPool pool, DbConnection owningObject, DbConnectionOptions options, DbConnectionPoolKey poolKey, DbConnectionOptions userOptions)\u000a at System.Data.ProviderBase.DbConnectionPool.CreateObject(DbConnection owningObject, DbConnectionOptions userOptions, DbConnectionInternal oldConnection)\u000a at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest(DbConnection owningObject, DbConnectionOptions userOptions, DbConnectionInternal oldConnection)\u000a at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, UInt32 waitForMultipleObjectsTimeout, Boolean allowCreate, Boolean onlyOneCheckConnection, DbConnectionOptions userOptions, DbConnectionInternal& connection)\u000a at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, TaskCompletionSource 1 retry，DbConnectionOptions userOptions，DbConnectionInternal＆amp; connection）\ u000a at System.Data.ProviderBase.DbConnectionFactory.TryGetConnection（DbConnection owningConnection，TaskCompletionSource 1 retry, DbConnectionOptions userOptions, DbConnectionInternal oldConnection, DbConnectionInternal& connection)\u000a at System.Data.ProviderBase.DbConnectionInternal.TryOpenConnectionInternal(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource 1在SystemADataLayer.SQLHelper.GetMultipleResultSets上的System.Data.SqlClient.SqlConnection.Open（）\ u000a处的System.Data.SqlClient.SqlConnection.TryOpenInner（TaskCompletionSource 1 retry)\u000a at System.Data.SqlClient.SqlConnection.TryOpen(TaskCompletionSource 1重试）\ u000a处重试（DbConnectionOptions userOptions）\ u000a字符串strSQlSPName，字典2& params, List 1 outParams）在D：\ TFS SAAS \ HighriseLicensing- \ DataAccessLayer \ SqlHelper.vb：第162行\ u000a at DataAccessLayer.LoginDL.AuthenticateKey（String key，Int32 guid，String userid，Int32 Mode））在D：\ TFS SAAS \ HighriseLicensing- \ DataAccessLayer \ LoginDL.vb：在D：\ TFS SAAS \ HighriseLicensing- \ BusinessLogicLayer \ LoginBL.vb：line 18 \ u000a at中的BusinessLogicLayer.LoginBL.AuthenticateKey（String key，Int32 guid，String userid，Int32 Mode）中的第20行\ u000a Lincensing.GetFaith.CheckKey中的Lincensing.GetFaith.CheckKeyvalidity（字符串键，Int32 guid，字符串InstallationId，Int32模式）在D：\ TFS SAAS \ HighriseLicensing- \ Lincensing \ GetFaith.asmx.vb：第53行\ u000a（字符串键， Int32 guid，String InstallationId，Int32 Mode）在D：\ TFS SAAS \ HighriseLicensing- \ Lincensing \ GetFaith.asmx.vb：第23行\ u000a ---内部异常堆栈跟踪结束---“

一件重要的事情是，当我从应用程序登录时，此服务正常工作，但如果我从应用程序注销，则会出现此错误。
