Safeguard Authentication Services 4.2 - Authentication Services for Smart Cards Administration Guide

Check the PKCS#11 library

Authentication Services for Smart Cards requires that you install a PKCS#11 driver to access cryptographic functions on the smart card.

To determine which PKCS#11 library is installed

1. Run the vastool smartcard info library command, as follows:

   # vastool smartcard info library
   Library: /usr/local/lib/libxltCk.so
   PKCS#11 version : 2.1
   PKCS#11 manufacturer : Gemalto
   PKCS#11 library description: Gemalto PKCS #11 Module
   PKCS#11 library version : 5.2

To determine whether the driver is working correctly

1. Run the vastool smartcard test library command.

   For example:

   # vastool smartcard test library
   Testing PKCS#11 library '/usr/local/lib/libxltCk.so':
   Checking PKCS#11 library may be dynamically loaded ... ok
   Checking PKCS#11 library contains necessary symbols ... ok
   Checking PKCS#11 function list can be obtained ... ok
   Checking PKCS#11 library version is compatible ... ok
   Checking PKCS#11 library can be initialized ... ok
   Checking PKCS#11 library can be finalized ... ok

Check the card

To obtain information about the smart card you are attempting to use for log in

1. Run the vastool smartcard info card command, as follows:

   # vastool smartcard info card
   label : MS interop NS card
   manufacturerID: Gemalto
   model : Access eg 32K v2
   serial number : 0001162CFF021982
   flags : { CKF_RNG CKF_LOGIN_REQUIRED CKF_USER_PIN_INITIALIZED
   CKF_DUAL_CRYPTO_OPERATIONS}
   Number of mechanisms on card: 18
   CKM_RSA_PKCS_KEY_PAIR_GEN
   CKM_RSA_PKCS
   CKM_RSA_X_509
   CKM_MD2_RSA_PKCS
   CKM_MD5_RSA_PKCS
   CKM_SHA1_RSA_PKCS
   CKM_DES_KEY_GEN
   CKM_DES_ECB
   CKM_DES_CBC
   CKM_DES_CBC_PAD
   CKM_DES2_KEY_GEN
   CKM_DES3_KEY_GEN
   CKM_DES3_ECB
   CKM_DES3_CBC
   CKM_DES3_CBC_PAD
   CKM_MD2
   CKM_MD5
   CKM_SHA_1

   This displays information about the type of card inserted and the supported cryptographic operations.

To determine whether a particular card can be used with Authentication Services for Smart Cards

1. Run the vastool smartcard test card command, as follows:

   # vastool smartcard test card

   Getting mechanisms ... ok
   Checking for required mechanisms ... ok
   Testing that card contains a user ... ok

Check login

To log in with a given smart card it must contain a certificate that contains the User Principal Name (UPN) of the user with which that the card can be used to log in.

To determine the user on a given card

1. Run the vastool smartcard info user command, as follows:

   # vastool smartcard info user
   UPN: sc-1-a@a.vas
   subject = /DC=vas/DC=a/CN=Users/CN=Smartcard 1. A
   issuer = /DC=vas/DC=a/CN=ca-root-a

   This displays information from the user certificate on the card.

   serialNumber = 5907991B000100000016
   notBefore = Oct 3 04:53:34 2006 GMT
   notAfter = Oct 3 04:53:34 2007 GMT
   signatureAlgorithm = sha1WithRSAEncryption
   keyAlgorithm = rsaEncryption

To determine whether this user is suitable for logging on to Active Directory

1. Run the vastool smartcard test user command, as follows:

   # vastool smartcard test user
   Testing user sc-1-a@a.vas
   Testing certificate validity ... ok
   Testing if PIN is required ... ok
   Enter PIN for sc-1-a@a.vas:
   Performing login to card ... ok
   Generating signature ... ok
   Verifying signature ... ok

   This retrieves the user information, tests whether the user on the card is user-enabled, and tests that the certificate can verify digital signatures generated by the card.

To simulate a full log on with Active Directory

1. Run the vastool smartcard test login command, as follows:

   # vastool smartcard test login
   Testing user sc-1-a@a.vas
   Testing certificate validity ... ok
   Testing if PIN is required ... ok
   Enter PIN for sc-1-a@a.vas:
   Performing login to card ... ok
   Creating ID for client with UPN 'sc-1-a@a.vas' ... ok
   Establish initial credentials using PKCS#11 ... ok
   Enabling debug for vastool commands

To enable additional debugging information

1. Run vastool with the -d option, as follows:

   # vastool -d 4 smartcard test login

   You can set the debug level from 1-6 for increasing levels of verbosity. Level 4 is generally sufficient for most smart card debugging.

Enable debugging for smart card login with PAM

The pam_vas_smartcard module supports an additional debug option that enables syslog to capture debugging information. This option is the same as the debug option supported by the pam_vas3 module. See Enabling diagnostic logging in the Authentication Services Administration Guide for more information on how to configure syslog for this option.
