True PAM can probally work for some. It seems opennms does not support
PAM? Then my guess is that is where Apache Axis and SOAP or a SOAP Proxy
come in.

I know you can do that. Not sure on the local account side. Pentaho's
looks to much like a Lockin App for anything. Not familiar with it

If he does not know he needs his brain checked out.

The bad part is adding them to every machine and I would be against

I guess the optimal thing to do is figure out every way all apps 
can authenticate and go from there. OR get a machine with hardware
that can handle all the runnng apps and auth at the machine level.
I'm just thinking in terms of a Blade Server. Just a side note I know
you can proxy SOAP requests but not sure on ldap.
