sc_auth

sc_auth(8)						    BSD System Manager's Manual 						sc_auth(8)

NAME

     sc_auth -- smart card authorization setup script

SYNOPSIS

     sc_auth accept [-v] [-u user] [-d domain] [-k keyname]
     sc_auth accept [-v] [-u user] [-d domain] -h hash
     sc_auth remove [-v] [-u user] [-d domain]
     sc_auth hash   [-k keyname]
     sc_auth list   [-v] [-u user] [-d domain]

DESCRIPTION

     sc_auth configures a local user account to permit authentication using a supported smart card.  Authentication is via asymmetric key (also
     known as public-key) encryption.  sc_auth works with signing keys, but not encryption keys.

     sc_auth can perform the following actions:

     accept   Associate a user with a public key on a card.  The key to use can be specified either by its name or its hash.

     remove   Remove all public keys associated with a user.

     hash     Print the hashes for all keys on all inserted cards.

     list     List all public keys associated with a user.

OPTIONS

     -u user  Specifies the user whose account is to be modified

     -d domain
	      Specifies the directory domain containing the user account

     -k keyname
	      Specifies a public key by its name

     -h hash  Specifies a public key by its hash

     -v       Verbose mode

NOTES

     sc_auth is a shell script.  It is intended to be modified by administrators to suit their local environments.

     sc_auth is only known to work with a local directory.  Consult the script's source for some limited guidance to using remote directories.

BUGS

     sc_auth hash might display the hashes of encryption keys as well as signing keys, even though sc_auth accept does not work with encryption
     keys.
