Hi!
I searched through tls_m.c for means to enter the token PIN for a PKCS11 token. I found a call to PK11_SetPasswordFunc(). The callback is set to tlsm_pin_prompt(), which by itself uses tlsm_get_pin(). tlsm_get_pin() only supports reading the PIN from file or via STDIN. To be usable within any form of gui, there would have to be some method to pass a GUI callback to ask for the PIN.
How would this work? Would you pass in a callback function with your private context, and this callback function would be called with the current MozNSS context + your provided context? What would be the possible return values from your callback? What should the code do depending upon each return value? Is there currently a way, via the OpenLDAP API, to pass in such a function and context?
For what it's worth, we need to add this feature for sasl_interactive_bind as well. Thus far, for the ldap_sasl interface all of the callback parameters have been passed on the function invocation, as opposed to being set by a separate ldap_set_option(). It makes for a clunky function signature, but seems safest in terms of re-entrancy...
Do you plan on implementing such a feature in the near future or is there a proposed way of setting such a callback method?
Kind regards, Silvan
