Re: Is iSphere plugin going to support Kerberos? -- WDSCI-L

Arco,

I opened PMR 91830,031,724 to address the problem to IBM.

Thanks to all who helped analyzing the problem.

Thomas.

Betreff: Re: [WDSCI-L] Is iSphere plugin going to support Kerberos?

I would be happy to open a PMR, however I'm not quite understanding the details of the problem ;-) What IBM product will jt400 be registrated under? It is kind of open source isn't it?

Arco,

That are great news, because it is what I expected to see. It seems
that it is time to contact IBM for that issue.

From my point of view it seems to be a defect that the following code

does not return a connection when Kerberos comes into play:

private Connection getISphereJDBCConnection() {

Connection jdbcConnection = null;

try {
IBMiConnection ibmiConnection =
comboConnections.getISeriesConnection();
jdbcConnection = ibmiConnection.getJDBCConnection(null, false);
} catch (SQLException e) {
}

return jdbcConnection;
}

But according to your response the following code returns a Kerberos
JDBC connection:

private Connection getKerberosJDBCConnection() {

Connection jdbcConnection = null;

try {
AS400JDBCDriver as400JDBCDriver = new AS400JDBCDriver();
if (DriverManager.getDriver("jdbc:AS400") == null) {
DriverManager.registerDriver(as400JDBCDriver);
}
IBMiConnection ibmiConnection =
comboConnections.getISeriesConnection();
AS400 system = ibmiConnection.getAS400ToolboxObject();
jdbcConnection = as400JDBCDriver.connect(system);
} catch (Throwable e) {
}

return jdbcConnection;
}

From my point of view there is a bug in IBMiConnection.

I wonder whether it makes sense to open a PMR when I do not have the
equipment to do the tests myself.

Thank you,

Thomas.

Hi Thomas,

I'm getting a result for the "Execute Kerberos Java" button: Loaded
from
SYSIBM.SYSDUMMY1: Y

Using the "Execute iSphere Java" results in the error below.

I uploaded an Eclipse test project (Test Kerberos Connection.zip)
to SourceForge at:

https://sourceforge.net/projects/isphere/files

If was great if somebody, who knows how to import the project to
Eclipse and to launch an Eclipse application in debug mode, could
download and import the project to RDi 9.5 or RDi 9.6.

The project adds a "Tools/400 -> Kerberos Test" view, which
contains two
buttons:

Execute iSphere Java
Execute Kerberos Java

The first one uses the original iSphere Java code to get a JDBC
connection for executing a "select * from sysibm.sysdummy1" statement.
It uses the getJDBCConnection() method of class IBMiConnection to
get a JDBC connection.

The second button registers the AS400JDBCDriver JDBC driver and
uses method getAS400ToolboxObject() of class IBMiConnection to get
an AS400 object, which it passes to connect() of AS400JDBCDriver
for getting a JDBC connection.

I really would like to know if the second approach can connect to
an IBM i using Kerberos authentication.

Thomas.
