我正在尝试将使用 EntityFW 和 Oracle.ManagedDataAccess 的 Web api 连接到 Oracle 12c (12.2.0.1)
我必须使用带有以下参数的 Kerberos 身份验证
SQLNET.KERBEROS5_CONF=C:\temp\krb5.conf
SQLNET.KERBEROS5_CONF_MIT=TRUE
SQLNET.AUTHENTICATION_KERBEROS5_SERVICE=orakrb
SQLNET.KERBEROS5_CC_NAME=OSMSFT:
SQLNET.AUTHENTICATION_SERVICES=(KERBEROS5PRE,KERBEROS5)
即使我在AUTHENTICATION_SERVICES中有KERBEROS5
我认为使用下面的设置它实际上不起作用
SQLNET.KERBEROS5_CONF=C:\temp\krb5.conf
SQLNET.KERBEROS5_CONF_MIT=TRUE
SQLNET.AUTHENTICATION_KERBEROS5_SERVICE=orakrb
SQLNET.KERBEROS5_CC_NAME=MSLSA:
SQLNET.AUTHENTICATION_SERVICES=(KERBEROS5)
所以我的有效配置就像
SQLNET.KERBEROS5_CONF=C:\temp\krb5.conf
SQLNET.KERBEROS5_CONF_MIT=TRUE
SQLNET.AUTHENTICATION_KERBEROS5_SERVICE=orakrb
SQLNET.KERBEROS5_CC_NAME=OSMSFT:
SQLNET.AUTHENTICATION_SERVICES=(KERBEROS5PRE)
我的web.config中嵌入了以下内容
<oracle.manageddataaccess.client>
<version number="*">
<settings>
<setting name="sqlnet.kerberos5_conf" value="C:\temp\krb5.conf" />
<setting name="sqlnet.kerberos5_cc_name" value="OSMSFT://" />
<setting name="sqlnet.authentication_services" value="(Kerberos5pre)" />
<setting name="sqlnet.kerberos5_conf_mit" value="TRUE" />
<setting name="sqlnet.authentication_kerberos5_service" value="orakrb" />
</settings>
</version>
</oracle.manageddataaccess.client>
我根本没有经过身份验证（我验证了正在运行的用户并且它是正确的）

我设法使我组织的大多数工具都在 API 之外工作
- sqlplus（命令行）
- Python
- pycharm的datagrip
- 电源 BI
- SSIS
- ETC..
