Hello ppl, I need to make a simple Client server app using Corba.. and the clients have to be authenticated and authorised.. and I need to implement this urgently (school report). I have read a bit about Corba and its services, made a simple corba app and now wondering if there are any free java ORBs that have COS Security Serivice implemented.. It seems that the Sun SDK ORB does not, as well as JACorb, Mico does but it is C/C++ ORB. My teacher told me you are welcome to use other ORBs but the one with the SDK will do well.. SO I got confused..SUre this simple app. could be done using Java security/Crypto classes but this won't be much of Corba code.. Could anyone tell me what is the best way to do it? I found an article at [Oracle Docs], and they use JNDI, the namming server for authentication, but I it seems they are also using some of their spec. APIs And by the way, I think that the most usual way is to use IIOP over the SSL layer.. but this would complicate my task to write a description of the full authentication handshake in CSP.. Any CSP gurus? Can anyone help.. Come on GURUs, U all have been students!! Thanking in advance IIOP sec.
