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 
 
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
