Standalone Authentification Method

Prerequisites

The following files are required:

• Root certificate and intermediate CA certificates, as applicable

• File cn_map which contains mappings of common names to UPN names for each smartcard certificate

Creating the cn_map File

->Create a file named cn_map in which each line is in the format <common name> -> <logon name> where

• <common name> is the common name part of the certificate's subject
  Example from a client certificate:
  

  

• <logon name> is the UPN name of the SubjectAltName extension of the certificate. The UPN name is dependent on whether Enterprise Kerberos names are enabled or disabled (the setting is described under Configuring the Devices):

  • When Enterprise Kerberos names are enabled, the user domain may differ from the default domain. In the following example, the user's domain is test.mail, while the default domain is MY.DOMAIN: testuser@test.mail@MY.DOMAIN
    Example from a client certificate:
    

    

  • When Enterprise Kerberos names are disabled, the user domain is the same as the default domain. Example: testuser@MY.DOMAIN  

Example line: Test User -> testuser@test.mail@MY.DOMAIN

Transferring the cn_map File to the Devices

The cn_map file must be located in the directory /etc/pam_pkcs11/cn_map. This can be achieved via UMS file transfer.

To transfer the cn_map file to the devices: 

1. In the UMS structure tree, go to Files and in the context menu, select New file.
   

   

2. In the New file dialog, configure the settings as follows:
   

   • Local file: Local file path of the certificate. Use the file chooser by clicking

     .

   • Device file location: /etc/pam_pkcs11/cn_map
     

     

3. Click Ok.
   The file object is created in the UMS.
   

4. In the UMS structure tree, select the endpoints for which you want to configure the local login with a smartcard certificate. For mass deployment, it is recommended to use a directory containing the endpoint devices or a profile (see Creating Profiles).
   

5. In the  Assigned objects  area, click 

   

   .
   

6. Under  Files, select the file object using the 

   

    button: 

   

7. Click Ok.
   

8. In the  Update time  dialog, select  Now  and click  Ok.
   The cn_map file is transferred to the endpoint device.

Transferring the Certificate Files to the Devices

Registering the Certificate Files as File Objects

To transfer the certificate files to the devices, perform the following steps for each certificate file:

1. In the UMS structure tree, go to Files and in the context menu, select New file.
   

   

2. In the New file dialog, configure the settings as follows:
   

   • Local file: Local file path of the certificate. Use the file chooser by clicking

     .

   • Device file location: /etc/pam_pkcs11/cacerts /

     

3. Click Ok.
   The file object is created in the UMS.

Assign the Certificate Files to the Devices

1. In the UMS structure tree, select the endpoints for which you want to configure the local login with a smartcard certificate. For mass deployment, it is recommended to use a directory containing the endpoint devices or a profile (see Creating Profiles).

2. In the  Assigned objects  area, click 

   

   .

3. Under  Files, select the required file objects using the 

   

    button: 
   

   

4. Click  Ok.
   

5. In the  Update time  dialog, select  Now  and click  Ok.
   The certificates are transferred to the endpoint device.

Configuring the Devices

To enable local login with a smartcard certificate, you must configure the devices appropriately. For mass deployment, it is recommended to use a profile.

1. Go to Security > Smartcard > Middleware and select the middleware to be used.

2. Go to System > Registry > auth > login > pkcs11 (registry key: auth.login.pkcs11) and activate Login with smartcard certificate.

3. Go to System > Registry > auth > login > pkcs11_cert_policy (registry key: auth.login.pkcs11_cert_policy) and enter the methods for certificate verification that are to be used. For further information, see the documentation in https://github.com/OpenSC/pam_pkcs11.

4. If Kerberos enterprise names are used, go to System > Registry > auth > login > krb5_enterprise and activate Allow enterprise names.

Debugging

->If you need to debug the smartcard certificate login, go to System > Registry > auth > login > pkcs11_debug (registry key: auth.login.pkcs11_debug) and activate Enable debugging of smartcard certificate login.
Logging messages will be available via syslog.
