The ocf.client.default.authmechanism property determines the default authentication sequence used for all valid cards during login to the client application.
The Smart Cards Used checklist, available from the Configure Clients: CDE dialog box, shows all smart card types currently activated for ocfserv.
The card_name Authentications list shows the available authentication mechanisms for the card type you selected from the Smart Cards Used list.
The order of authentication mechanisms in the card_name Authentications list is the actual order of the authentication sequence that the ocfserv tries when a user accesses this client application.
See "How to Change the Default Client Authentication Sequence for Valid Cards (Console)" for step-by-step instructions for changing this property.
