Problem: After upgrading from RHEL 7.4 to RHEL 7.5 smartcard no longer works in an environment where FIPS is required. The previously working cards are no longer detected although all of sctool checks come back successful.
Cause: This is not a Centrify issue. This is a known issue with Redhat. For updates on this bug please reference the bug HERE
Workaround: Revert back to RHEL 7.4 until the fix is in place for RHEL 7.5
