使用Anaconda版本的Python 3创建到MSSQL服务器的ODBC连接时,我遇到了一个错误:
pyodbc.Error:(“HY000”,“用于SQL ServerSSPI提供程序的HY000ODBC驱动程序17 :没有Kerberos凭据可用”(默认缓存: KEYRING:persistent:1918003883) (851968) (SQLDriverConnect))
服务器已经通过SSSD加入了Windows域和Kerberos领域。我可以将SSH放入服务器,并使用kinit检索TGT。我甚至可以看到使用klist的凭证缓存。但是python进程似乎既找不到Kerberos TGT,也找不到Kerberos凭据缓存。
设置:

isql。我负责isql MyDSN和那个连接。yum安装;另一个通过conda安装)。默认情况下,它将使用conda,但我强迫它使用带有LD_PRELOAD的系统unixODBC包。同样的错误。conda中创建了一个单独的环境。这起作用了!还是不知道为什么。py3-unixodbc.trace

迟回复,但我希望有人会发现它有用。
对我来说,krb5包也解决了这个问题,它与系统范围的kerberos安装共存:将它从环境中删除解决了问题(我试图使它工作,但没有成功)。
