Question:
A smart card works fine on Windows and Mac systems, but does not work on RHEL 6.5.
The login screen shows a PIN prompt, but will shake with the following message:
"the return value should be ignored by pam dispatch"
Are smart cards supported on RHEL 6.5?
Answer:
This can happen when the samAccountName is different from the UPN. Usually the samAccountName should be the same as the UPN.
As a workaround, change the AD account to match with the samAccountName, or use Centrify DirectControl 5.1.2 (which does not have this issue).
Note: Centrify has fixed this issue in Suite 2014.1
