Re: Extending Open LDAP

Hi Philip,

Openldap has several generic backends that allow you to couple PIDS to
OpenLDAP without modifying any OpenLDAP code. Instead you write a shell, perl
or tcl script to adapts the request to a request for your PIDS system.
In your case the new CORBA backend I'm working on also might be interesting.
It relays the search and other LDAP requests to a CORBA interface. This will
allow you to put the adapter anywhere you like.
You can have a look at the IDL specification of the interface at:
http://home.lifeline.nl/bastiaan/openldap/corba/openldap.idl .  IDLDoc'ed API
documentation is available at:
The implementation is based on OmniORB2 but it shouldn't be too difficult to
port to another ORB. Currently only the search function has been implemented,
but I hope to publish a more complete version soon.
