debug
Turns on debugging.
debug_file=file
File name to write debug to, the file must exist and be a
regular file. Defaults to stdout.
mode=[client|challenge-response]
Mode of operation, client for OTP validation and
challenge-response for challenge-response validation. Defaults to
client.
authfile=file
Location of the file that holds the mappings of YubiKey
token IDs to user names. The format is
username:first_public_id:second_public_id:... Default location of the file is
$HOME/.yubico/authorized_yubikeys.
id=id
Your API client identity for the validation server.
key=key
Your client key in base64 format. The client key is also
known as API key, and provides integrity in the communication between the
client (you) and the validation server. If you want to get one for use with
the default YubiCloud service, please go to:
https://upgrade.yubico.com/getapikey/
alwaysok
Succeed with all authentication attempts
(dangerous, presentation mode).
try_first_pass
Before prompting the user for their password, the module
first tries the previous stacked module´s password in case that
satisfies this module as well.
use_first_pass
Forces the module to use a previous stacked modules
password and will never prompt the user - if no password is available or the
password is not appropriate, the user will be denied access.
always_prompt
If set, don’t attempt to do a lookup to determine
if the user has a YubiKey configured but instead prompt for one no matter
what. This is useful in the case where ldap_bind_as_user is enabled but this
module is being used to read the user’s password (in a YubiKey+OTP auth
scenario).
nullok
Don’t fail when there are no tokens declared for
the user in the authorization mapping files or in LDAP. This can be used to
make YubiKey authentication optional unless the user has associated
tokens.
ldap_starttls
If set, issue a STARTTLS command to the LDAP connection
before attempting to bind to it. This is a common setup for servers that only
listen on port 389 but still require TLS.
ldap_bind_as_user
Use the user logging in to bind to ldap. This will use
the password provided by the user via PAM. If this is set, ldapdn and uid_attr
must also be set. Enabling this will cause ldap_bind_user and
ldap_bind_password to be ignored.
urllist=list
List of URL templates to be used. This is set by calling
ykclient_set_url_bases. The list should be in the format:
https://api1.example.com/wsapi/2.0/verify;https://api2.example.com/wsapi/2.0/verify
url=url
This option should not be used, please use the urllist
option instead. Set the URL template to use, this is set by calling
ykclient_set_url_template. The URL should be set in the format
https://api.example.com/wsapi/2.0/verify?id=%d&otp=%s
capath=path
The path where X509 certificates are stored. This is
required if https or ldaps are used in url and
ldap_uri, respectively.
cainfo=file
Option to allow for usage of a CA bundle instead of
path.
proxy=proxy
The proxy to connect to the validation server. Valid
schemes are http://, https://, socks4://, socks4a://, socks5:// or socks5h://.
Socks5h asks the proxy to do the DNS resolving. If no scheme or port is
specified HTTP proxy port 1080 will be used. Example:
socks5h://user:pass@10.10.0.1:1080
verbose_otp
Show the One-Time Password when it is entered, i.e. to
enable terminal echo of entered characters. You are advised to not use this,
if you are using two factor authentication because that will display your
password on the screen. This requires the service using the PAM module to
display custom fields. This option can not be used with OpenSSH.
ldap_uri=uri
The LDAP server URI (e.g. ldap://localhost).
ldap_server=server
The LDAP server host (default LDAP port is used).
Deprecated. Use ldap_uri instead.
ldapdn=dn
The distinguished name (DN) where the users are stored
(eg: ou=users,dc=domain,dc=com). If ldap_filter is used this is the
base from which the subtree search will be performed.
ldap_clientcertfile=clientcertfile
The path to a client cert file to use when talking to the
LDAP server. Note this requires ldap_clientkeyfile to be set as
well.
ldap_clientkeyfile=clientkeyfile
The path to a key to be used with the client cert when
talking to the LDAP server. Note this requires ldap_clientcertfile to
be set as well.
user_attr=attr
The LDAP attribute used to store user names
(eg:cn).
yubi_attr=attr
The LDAP attribute used to store the YubiKey ID.
yubi_attr_prefix=prefix
The prefix of the LDAP attribute’s value, in case
of a generic attribute, used to store several types of IDs.
token_id_length=length
Length of ID prefixing the OTP (this is 12 if using the
YubiCloud).
ldap_bind_user=user
The user to attempt a LDAP bind as.
ldap_bind_password=password
The password to use on LDAP bind.
ldap_filter=filter
A LDAP filter to use for attempting to find the correct
object in LDAP. In this string %u will be replaced with the username.
ldap_cacertfile=cacertfile
CA certitificate file for the LDAP connection.
chalresp_path=path
Path of a system-wide directory where challenge-response
files can be found for users. Default location is $HOME/.yubico/.
mysql_server=mysqlserver
Hostname/Adress of mysql server. Example 10.0.0.1
mysql_port=mysqlport
Network port of mysql server.
mysql_user=mysqluser
User for accessing to the database. Strongly recommended
to use a specific user with read only access.
mysql_password=mysqlpassword
Mysql password associated to the user.
mysql_database=mysqldatabase
the name of the database. Example : otp
