KB-4323: Unable to use smartcard on RHEL 6.5

Authentication Service ,  

12 April,16 at 11:07 AM

Applies to: Centrify DirectControl 5.1.3 
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?
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
