With sudo and pam_musclecard, the user is prompted for the smartcard PIN which unlocks the private key for a nonce challenge. The actual prompt is "Please enter pin," as I noted above. sudo works fine in this environment.
I did note that when gksu is run from the command-line that the PIN prompt is dumped to stderr by gksu. Does this help? I can help in testing if you need it. -- gksu not prompting when pam_musclecard in use https://launchpad.net/bugs/52018 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
