[Pcsclite-muscle] Smartcard PAM module load failed after update pcsc-lite from 1.5.2 to 1.7.4 on Redhat6.6

[Zhaohan Ren]

Hi

I configured /etc/pam.d/su on Redhat6.6 64bit to do authentication by PIV smartcard:

vi /etc/pam.d/su
#%PAM-1.0
auth            sufficient      pam_rootok.so
auth            sufficient      pam_pkcs11.so debug


Also I replace the module with vender's:
vi /etc/pam_pkcs11/pam_pkcs11.conf:
  pkcs11_module coolkey {
    module = /usr/lib64/pkcs11/libcmP11.so;


Everything works well within the original pcsc-lite-1.5.2 until I downloaded and updated pcsc-lite to 1.7.4(https://alioth.debian.org/frs/?group_id=30105#title_pcsclite) manually. Below is my steps:
./configure -prefix=/usr/
make
make install
service pcscd restart

[root at redhat-66-sc-login pcsc-lite-1.7.4]# pcscd -v
pcsc-lite version 1.7.4.

Then I found smartcard PAM authentication always failed:

Does anyone have any idea about this issue? Thanks in advance!
