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.
