apache2 mod_gnutls https 服务实际上成功运行，但在尝试从 pkcs11 URL 读取私钥时始终返回此错误：
[Wed Jan 20 13:26:25.268236 2016] [gnutls:emerg] [pid 5232:tid 140334984677248] GnuTLS: Failed to Re-Import Private Key URL 'pkcs11:model=SoftHSM;manufacturer=SoftHSM;serial=1;token=GnuTLS-Test;id=%3e%2d%3d%e4%2b%8b%a0%7c%7c%56%08%95%aa%aa%47%db%15%a2%b9%84;object=GnuTLSTest2;object-type=private': (-300) PKCS #11 error.
使用 apache2 2.4.x 与 mod-gnutls 0.7.2 + gnutls 3.3.x
操作系统：Ubuntu Vivid
有趣的是，它不会返回证书的此类错误，只会返回私钥。
那么有什么想法吗？
更新：
这是来自 mod_gnutls.conf 的配置文件：
<IfModule mod_gnutls.c>
# The default method is to use a DBM backed cache. It's not super fast, but
# it's portable and doesn't require another server to be running like
# memcached
#GnuTLSP11Module /usr/lib/softhsm/libsofthsm.so
#GnuTLSPIN 1234
GnuTLSCache dbm /var/cache/apache2/gnutls_cache
# mod_gnutls can optionaly use a memcached server to store SSL sessions.
# This is useful in a cluster environment, where you want all your servers to
# share a single SSL session cache
#GnuTLSCache memcache "127.0.0.1 server2.example.com server3.example.com"

答案1
您的 pkcs11 库已被注释掉：
GnuTLSP11Module /usr/lib/softhsm/libsofthsm.so
因此mod_gnutls无法读取 HSM 上的密钥。您也可以取消注释该引脚：
GnuTLSPIN 1234
显然将其更改为您选择的 PIN。
