“无法找到与可用硬件匹配的合适指纹”错误

我有一台配备 UPEK 指纹读取器的 ThinkPad T61。我运行的是 ubuntu 9.10，安装了 fprint。除了在启动或结束会话时实际登录笔记本电脑外，一切正常（我可以刷指纹来成功验证任何权限对话框或“sudo”提示）。

我在 gnome 登录下面收到一条错误消息，提示

"Could not locate any suitable fingerprints matched to available hardware."

是什么原因造成的？

以下是 /etc/pam.d/common-auth 文件的内容

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.).  The default is to use the
# traditional Unix authentication mechanisms.
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules.  See
# pam-auth-update(8) for details.

# here are the per-package modules (the "Primary" block)
auth sufficient pam_fprint.so
auth    [success=1 default=ignore]  pam_unix.so nullok_secure
# here's the fallback if no module succeeds
auth    requisite           pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth    required            pam_permit.so
# and here are more per-package modules (the "Additional" block)
auth    optional    pam_ecryptfs.so unwrap
# end of pam-auth-update config
#auth sufficient pam_fprint.so
#auth required pam_unix.so nullok_secure

答案1

当您安装 Ubuntu 时，您是否对用户目录进行了加密？

答案2

尝试注释掉以下行：auth adequate pam_fprint.so

这将从您的 PAM 身份验证中删除指纹身份验证
