RE: Websphere authenticating to a remote as/400 and Envoy

Thanks David. How does Kerberos differ from SSL?

Todd,

I can't tell you how you would do this with WebSphere, but with Tomcat
you would create a Realm. There are three or four that come with Tomcat
and they are pretty easy to create. The realm receives the user
principle which gives you the information they keyed into the security
challenge in a browser. If you use Basic the password comes through
clear, if you use Digest it will be an MD5 digest of the password. You
are free to use that information to check against anything you want. To
authenticate against an iSeries profile, I you will probably need the
clear text password -- this is dangerous and hard to secure. 

If you are running on another box, you limit how you can authenticate
and generally have clear text passwords somewhere or kerberos. With
kerberos you can get around this using the SPNEGO protocol to talk to
the browser. There is at least one commercial application that
implements SPNEGO but the only free option I know of is Apache.

I see. So, just so I completely clear, they are not authenticating
against
400 profiles, they are using bsd user accounts, in the case of the one
running FreeBSD? That makes sense. I was wondering how one would get
past
this limitation.

Todd, as far as I know a web application server will only authenticate
against the box it is running on.  We've got two other PSC/400
installations doing just that: one is running Tomcat on a FreeBSD
machine, while ITT Aerospace is running WebSphere on one iSeries and
the
applications on another.
