PAM unable to dlopen(/lib64/security/pam_fprintd.so)
2016-04-07lib64/security/pam_fprintd.so
1、/var/log/secure里面包含大量错误：
Apr 7 08:01:01 iZ25c6u4y38Z crond[32054]: PAM adding faulty module: /lib64/security/pam_fprintd.so
Apr 7 08:10:01 iZ25c6u4y38Z crond[32080]: PAM unable to dlopen(/lib64/security/pam_fprintd.so)
Apr 7 08:10:01 iZ25c6u4y38Z crond[32080]: PAM [error: /lib64/security/pam_fprintd.so: cannot open shared object file: No such file
2、ll /lib64/security/pam_fprintd.so确实没有这个文件
3、vi /etc/pam.d/system-auth-ac里面确实包含pam_fprintd.so，注释后搞定
#auth sufficient pam_fprintd.so
