Subject RE: S4U2Proxy and S4U2Self on ApacheDS
Date Mon, 13 May 2013 22:30:57 GMT
Thanks for the quick response. It seems I can't use these two protocols at the moment then.

So let me describe my situation and maybe someone will give me some hint.

I have a service A that will launch a bunch of jobs for its client. The jobs will interact
with a Kerberos secured service B. I was thinking about deploying a service principal for
A onto the host where A is running and have it impersonate its clients using S4U2Proxy and
S4U2Self protocols.

Since S4U2Proxy and S4U2Self is not yet working on ApacheDS, then the other option I can think
of is to deploy a key for each client of A onto the host where A is running. So A will request
Kerberos ticket for its client and use the ticket to access service B. The trouble is that
everytime I add a new client for A, I have to add a key entry into the keytab, which is a

Does anyone knows better way to do it?

I think that might have been me.  While I was able to generate the tickets, they were never
accepted by IIS (when ISA tickets were) so I gave up.  But I was more focussed on the client
APIs, not in having ApacheDS being a KDC.

Does anyone know if ApacheDS support this two protocols?  In 2010, someone mentioned about
trying to implement these protocols. Are the work done? If so, how can I test them?
