Hi,
After many hours of pouring over online documentation, I finally
successfully setup Globus 4.2.1 on a Linux cluster based on torque. The
final goal is to be able to run the LONI Pipeline
(http://pipeline.loni.ucla.edu/) on the cluster using the Java DRMAA
interface implemented in Gridway. At this point the Java DRMAA
interface within Gridway appears to be functioning properly and all I
need to do is setup the LONI Pipeline to work with Gridway. This is
where I'm stuck. Specifically...
1. As outlined in the LONI Pipeline server guide, authentication within
the LONI Pipeline is performed using the Java Authentication and
Authorization Service (JAAS), which requires a LoginContext and LoginModule.
2. A google search for globus and JAAS reveals the wsaaJavaPDP.pdf file
which discusses the Globus JAAS authorization class implemented in
org.globus.wsrf.impl.security.authorization.UsernameAuthzPDP. The pdf
describes how to create custom LoginContext and LoginModule classes
using examples in the unit tests within the source. I was unable to
find the documented examples within the 4.2.1 source files.
Furthermore, it is unclear exactly what globus files need to be modified
to get this working.
3. The way I envision this setup working is that the LONI Pipeline
connects to the Globus WS container using JAAS, which provides
authorization for running Globus within Gridway and DRMAA without
specifically calling grid-proxy-init, but it is very unclear how I might
go about implementing this.
Any assistance provided on this scenario will be greatly appreciated.
Thanks in advance!
Don
