There's one for gnumed in python. The resources I used was  reading the 
**openemed** java implementation of pids on sourceforge.
getting a orb with a python biinding ( omniorb on sourceforge   which has GNU 
licensing),  using the omniorb idl  skeleton code
generator on the  OMG  idl definitions found in openemed or the OMG website, 
and tweaking them slightly for omniidl to work.

Then read the documentation from *openemed*  or from OMG about the pids 
specification , and look at the
openemed java implementation for comparison.  I used an IDE to browse the 
openemed source code.

Then , have a target database for your pids , and do  mapping code within your 
implementation of the pids server .
My target was the gnumed demographics schema, and the preferred language was 
python.
The omniidl.py  generates python objects that have attribute and method names 
as found in the PIDS Specification.

The python objects generated by omniorb idl can be read , and I think you can 
do   x.__dict__  to try to guess how the
idl  generated  python objects are called, on the python command line ( after 
importing the generated package).
Knowing the corba type system as per java sdk 1.4+ ,  org.omg.*  packages may 
help.

I think the fairly short user's guide from omni orb py , helps to.

You can find the python pids-to-gnumed code in cvs 
gnumed/gnumed/test-area/corba  .

Hope it's of use.


P.S. I never got around to using it for authentication;  I think that is 
actually another omg service. 

But Openemed does implement some sort
of security service related to pids access, but I 
didn't try to learn it.
