Re: JSS/NSS locks my smart card after 1 bad pin entry

Thank you so much. I am in the same situation exactly. return null is the key in getPasswordAgain(info). If you put a breakpoint here you can see it enters here to ask the password again.

I think, it will also work if we implement a logic of showing a dialog to ask the user the password again, but return null is the simpler approach.
