LEXMARK CLOUD AUTHENTICATION
Readme for version 5.8.1

1. OVERVIEW

This Readme file pertains to the current release of the LEXMARK CLOUD
AUTHENTICATION application.

Lexmark Cloud Authentication is an embedded solution that can be installed
on printers that support the Lexmark Embedded Solutions Framework (eSF).
Cloud Authentication locks out the printer until a user authenticates with a
badge or login credentials. It secures access to the printer using a
user-defined security server.

b. Memory: The printer must have a minimum of 256MB of RAM.

c. Card reader and driver: This application requires a card reader and
an appropriate driver for card login. To
obtain these items, go to www.lexmark.com,
and then click "Contact Us" at the bottom of
the page.

4. LIMITATIONS AND COMPATIBILITY OF THE RELEASE

a. The card reader and driver are sold separately. To purchase the card
reader, go to www.lexmark.com, and then click "Contact Us" at the
bottom of the page.

b. Users must register with a badge through a card reader or have valid
login credentials to use a printer. If a different card reader model
is used, then it may not recognize the badge. Either use the same
card reader model, or register the card again when prompted.

c. Logging in to a printer using Cloud Authentication is not necessary
to perform host-based printing.

d. Login Screen Text is limited to 256 characters. Text that is more than
256 characters does not appear properly on the screen.

e. When Compatibility View in Internet Explorer is enabled, the
configuration page for the application may not appear properly. For
best results, disable Compatibility View.

f. If public permissions of copy and fax functions are changed, then you
must save the configuration page for the application again. This action
applies only if the Allow Copy Without Login or the Allow Fax Without
Login setting is enabled before changing the permissions of those
functions.

g. Supported web browsers:
* Google Chromeâ„¢ version 43.x or later
* Mozilla Firefox version 38.x or later
* Internet Explorer version 11.x or later

h. Cloud Authentication is set as the default login in Security settings.

i. If Cloud Authentication is set as a Pluggable Auth Module (PAM), then
it must not coexist with Card Authentication or any other authenticator
app.

j. When installing the Cloud Authentication application, disable Display
Customization.

k. To access the Embedded Web Server, use your host name with the domain.

l. When the network is disconnected, the IP address on the lock screen
does not update automatically.

m. During card registration, tap the login icon to show the login screen.

n. Cloud Authentication remains accessible in Security Settings, despite
its unregistered status as Pluggable Auth Module (PAM).

o. Users utilizing Cloud Authentication as Non-Pluggable Auth Module
(NONPAM) without additional authenticators may encounter the following
issues:
* Cloud Authentication is unable to terminate sessions via logout
in the absence of another set PAM.
* Lexmark Cloud Services Apps such as LTX are unable to log in a
different user until the session times out.

p. The idle screen of the alternate authenticator does not appear if Cloud
Authentication is installed first.

q. Navigation or focus on "Register via email" is unavailable.

r. Immediately tapping the same card after successful card registration
does not log out the user.

s. The Keyboard Badge Event may trigger twice intermittently when both
Cloud Authentication and Card Authentication are installed.

t. On Cloud Fleet Deployment, clearing the "Enable pluggable
authentication module" option also disables the idle screen in the
current generation of devices.

u. Lexmark Cloud Services (LCS) apps cannot clear the session when there
is no available main authentication module.

v. Card swipe is limited only to Keyboard/Omnikey5427ck Reader Driver when
Cloud Authentication is set to NONPAM.

w. There are no permissions to launch LCS apps after Cloud Fleet Deployment
when coexisting with other authentication modules.

5. FUNCTIONING AS DESIGNED

a. If Cloud Authentication is set to NONPAM, then Badge login may not
function if Lexmark card reader drivers do not support the printer's
card reader device.

b. Card Authentication Client Secret and LDAP Login Password have been
successfully imported back via VCC Import Configuration.

c. If Cloud Authentication is set to NONPAM and there are no LCS apps
initiating the Cloud Authentication login process, then users may be
unable to log in via Cloud Authentication.

d. If Cloud Authentication is set to PAM and Card Authentication is
installed on the device with its idle screen enabled (even if stopped),
then the idle screen of Cloud Authentication is automatically disabled.

e. If a card reader device is connected to the printer and the keyboardReader
is unable to claim itâ€”whether due to uninstallation or being stoppedâ€”then
the device may not be detected, preventing users from logging in with a
badge. To resolve this, reinsert the card reader or restart the printer.

f. Cannot perform Native Email if SMTP Server Authentication is set to
OAuth2.0 and User-initiated email is set to Use Device SMTP Credentials.

g. If Login Code Instructions in the Secure Login menu is set to â€œE-mail
This,â€ then the sender name appears as Unknown, and the email is
delivered to the Junk folder.
