Issue

• We are able to authenticate users via LDAP and SPNEGO with Kerberos on the WebApp. The application needs to access to DB2 via JDBC universal Drivers (type 4).

• We tried several DS configuration but the result is always the same: DS is not able to obtain user credential and we get: Invalid credential.

• DS Example :

      <xa-datasource>
          <jndi-name>DB2XADS</jndi-name>
          <xa-datasource-class>com.ibm.db2.jcc.DB2XADataSource</xa-datasource-class>
          <xa-datasource-property name="databaseName">DB2T</xa-datasource-property>
          <xa-datasource-property name="serverName">TEST</xa-datasource-property>
          <xa-datasource-property name="driverType">4</xa-datasource-property>
          <xa-datasource-property name="kerberosServerPrincipal">db2/DB2T@MY.DOMAIN.IT</xa-datasource-property>
          <xa-datasource-property name="securityMechanism">11</xa-datasource-property>
          <security-domain>MySecurityDomain</security-domain>
          <xa-datasource-property name="PortNumber">60014</xa-datasource-property>
          <isSameRM-override-value>false</isSameRM-override-value>            
          <metadata>
              <type-mapping>DB2</type-mapping>
          </metadata>
      </xa-datasource>
