Password caching policy
  • Under
    Client Policy
    , if
    Enforce session settings
     is not enabled, clients can save their encrypted password to disk, regardless of what settings are configured under
    Session Settings
    .
  • Under
    Password Caching Options
     if you set
    Cache password within application for
     for a specific amount of time, after a successful logon the submitted credentials are cached until one of the following events occurs:
    • The specified credential cache duration expires.
    • The server address of the configuration within the application changes.
    • The user name of the configuration within the application changes.
    • The BIG-IP® Edge Client® user switches between configurations and makes a new connection.
    • The configuration is deleted and a new one is created.
  • On the
    Chrome OS device
    , even if a user clicks
    Disconnect
    , then terminates the application or restarts the device, cached credentials are not cleared until the specified cache time.
Client certificates
Client certificate authentication is supported in Web Logon mode with or without a password. In standard logon mode, certificates are supported, but a password is required. A password (including an empty password) can be saved in the configuration.

About defining a server from a URL

You can add BIG-IP® server definitions to F5 Access from a URL. You can provide these URLs to users, so they can create and/or start VPN connections without having to manually start the application.
Use the following URL and parameters to create a server:
Special characters in parameters must be URL-encoded.
The syntax to define a server from a URL follows.
server
The server address is either a DNS name or an IP address.
name
An optional description of the server.
username
An optional parameter used to specify the user name with which to start the connection. When the
username
 is specified without a
password
, then an authentication prompt is displayed. If no
username
 is specified during server creation, the user is prompted for it at session initiation, if required.
password
An optional parameter used to specify the password with which to start the server connection. When the
password
 parameter is specified, it is used as a one-time password and not saved in the configuration.
logon_mode
Specifies whether the logon mode is the standard logon (
native
) or web logon (
web
). The default logon mode is
native
.

Examples of defining a server from a URL

The following examples illustrate how to define servers for F5 Access connections from a URL.
Create a server at
access.siterequest.com
 in Web Logon mode:
http://cdn.f5.com/product/apm/edgeclient/chromeos/api/create?server=access.siterequest.com&logon_mode=web
Create a server named ChromeAccess at:
access.siterequest.com
In this scenario,
logon_mode
 is not specified, so native logon mode is assumed.
http://cdn.f5.com/product/apm/edgeclient/chromeos/api/create?name=ChromeAccess&server=access.siterequest.com
Create the same server with a user name, password, and certificate:
http://cdn.f5.com/product/apm/edgeclient/chromeos/api/create?name=ChromeAccess&server=access.siterequest.com&username=ChromeAccess&password=ChromeOSdemo&cert_issuer_cn=DemoIssuerCA
Create the same server with a user name and certificate:
http://cdn.f5.com/product/apm/edgeclient/chromeos/api/create?name=ChromeAccess&server=access.siterequest.com&username=ChromeAccess&cert_issuer_cn=DemoIssuerCA
Create the same server with a certificate:
http://cdn.f5.com/product/apm/edgeclient/chromeos/api/create?name=ChromeAccess&server=access.siterequest.com&cert_issuer_cn=DemoIssuerCA
