Decoupling PAM prompts from responses

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Is it possible to decouple the collection of prompts from the response
to them? It seems that you have to do both at once in the conversation
function.

I want to be able to grab the prompts and then respond to them with a 
seperate call.                                                        

Why? I am rewriting OpenSSH's PAM keyboard interactive auth method
to integrate better (currently it abuses the protocol a bit :). Auth
requests and responses can come asynchronously, and we use a callback
architecture to process them when they arrive. I can't make this fit
with the conversation function's need to deliver the prompts and expect
the replies within the same function.

Any help would be appreciated.
