There are a couple of known bugs/missing features in this package:

 - Sometimes the etsrvd daemon doesn't start. Make sure the pcscd
   daemon is running and try again.

 - Mkproxy: the default lifetime for grid proxies is 12 hours; however,
   the command-line syntax of openssl only allows an integer number
   of days. A patch has been sent to openssl to extend the syntax; see
   http://www.mail-archive.com/openssl-dev@openssl.org/msg22687.html

 - A bug in engine_pkcs11 makes it impossible to use PINs longer than
   11 characters; another bug prevents the use of more than one
   token at a time. See
   http://www.mail-archive.com/opensc-devel@lists.opensc-project.org/msg01855.html

 - You can't change the SO PIN under Linux.
