Features and enhancements in 2.0.3

ID number Description
463498 SAML authentication can now be performed within Edge Client to establish a VPN connection
The BIG-IP® Edge Client® application for mobile devices provide the following SAML support:
  • SP-initiated access only (e.g. APM acting as the SP).
  • Web Logon mode only.
  • Single Logout (SLO) is supported only when the logout action is initiated from the client.
453765 The admin or the user can now specify a client certificate to be used for WebLogon.
346136 On Demand VPN now works with "username + password" when a user enable the "Allow Password Caching" policy on the APM server.
475404 A user can now create VPN configurations without requiring users to specify the user name during creation. However, a user name entered from an authentication prompt will automatically be saved in the VPN configuration if the credentials were successfully authenticated and the connection was launched by the user within Edge Client (as opposed to being launched by URL scheme or VPN-on-Demand).
468486 Previously, there is no way to explicitly specify the logon mode of the VPN connection. If either username or certcn is specified as one of the URL parameters, Edge Client will implicitly use the native logon mode. Web logon mode would only be used if there is no user name or certificate specified.
In version 2.0.3, a logon_mode parameter can now be specified as part of the URL parameters. It allows the user to explicitly specify the logon mode as either web or native. An error message will be shown if any of the input parameters is not valid for the specified logon mode. If no logon_mode parameter is specified, the native mode will be selected as the default.

Behavior changes in 2.0.3

ID number Description
475017 Starting on iOS 7, domains entered in the Always Connect section have the same behavior as the Connect If Needed status. On iOS 8.x systems, domains entered in the Always Connect section are automatically moved to Connect If Needed status by the system after the VPN configuration is saved.

Known issues in 2.0.3

ID number Description
476549 The DNS address spaces are limited to 64 entries. When split tunneling is enabled, the Apple VPN framework only allow up to 64 entries for the DNS address space. Exceeding this number will generate warning messages in the device console log, such as the following:
Aug 22 10:54:18 iPad mDNSResponder[50] <Error>: mDNS_AddDNSServer: DNS server limit of 64 reached, not adding this server Aug 22 10:54:18 iPad mDNSResponder[50] <Error>: mDNS_AddDNSServer: DNS server limit of 64 reached, not adding this server Aug 22 10:54:18 iPad mDNSResponder[50] <Error>: mDNS_AddDNSServer: DNS server limit of 64 reached, not adding this server .
351545 When a user is prompted for password credentials, the cursor remains in the auto-filled username field when the cursor should be in the password field. This issue exists on the Apple Control UI.

Fixes in 2.0.3

464861 Previously, a user might notice the Per-App VPN connection is established but some websites or some of their content could fail to load. This issue as been fixed in 2.0.3.
