Unified Access enables you to access College applications, such as ICIS, from anywhere in the world, directly from your device, without requiring a VPN or remote desktop connection. 

The product that ICT is using to provide Unified Access is called Zscaler Private Access (ZPA). This service is currently only available for staff. Staff will receive a communication from ICT when they can start using the service. Find out if your account has been enabled by using our online checker tool.

Unified Access is available on College managed laptops and can be accessed from unmanaged or personal devices. Read the instructions below relevant to your device and operating system to get started. 

NOTE: Once activated you should not use the VPN (either vpn.ic.ac.uk, OpenVPN or Pulse VPN) at the same time as Unified Access (ZPA). Additionally, it should not be necessary to use Remote Desktop Connection (RDC) to connect to a desktop PC as Unified Access will provide access to services directly from your laptop.

  • Once complete the grey logo for Zscaler will appear in your task bar, this indicates that the software is installed but not connected.
  • Open the Zscaler app by clicking on the small grey logo in your task bar.
  • A dialog box will appear asking you to sign in, please use your College username in the format username@ic.ac.uk.

  • It is possible that the connection will fail on the first attempt, especially if you are connected to the VPN service. If you see a message reading “unable to complete enrolment at this time”. Please ensure that the VPN / Open VPN / Pulse connections you have are disconnected and allow the software to re-try the connection once the countdown is complete.
  • If this message does not go away, please contact the Service Desk on 020 759 49000. See example screenshot below of message.

  • When the software connects successfully you will receive a popup reading “information, Private Access is Connected”, and the Zscaler icon in the task bar will turn blue. 

  • This can be further verified in the Zscaler software by clicking the “Private Access” padlock symbol and checking that “Service Status” is showing as “ON”.

Installing Zscaler Client Connector on Linux

Having downloaded the .run installer file, open a terminal window and change into the download directory (often “Downloads”):

          cd Downloads

Make the file executable:

          chmod a+x <installerfilename.run>

Execute the file as the super user, ensuring to add the “userDomain” command line switch as this will prevent Zscaler prompting you for the domain every time you log in:

          sudo ./<installerfilename.run> --userDomain ic.ac.uk

Enter your password for sudo if prompted and follow the instructions to install the software.

 

 

 

 

 

 

 

 

 

 


Once installation is complete the Zscaler client should open automatically and prompt you to log in. Enter your username@ic.ac.uk as you would to connect to Office 365. You will be required to enter your password and may need to respond to a multi-factor authentication (MFA) request too.

 

 

 

 

 

 

 

 

 

 


Once connected you will see the Zscaler icon in the system tray will turn blue and under the “Private Access” (padlock icon) section within the client you will see the Service Status indicating “ON”.

 

 

 

 

 

 

 

 

 

 


Periodically you will need to reauthenticate, indicated by an exclamation mark over the Zscaler icon in the system tray (top right).

Click on the icon, followed by “Open Zscaler”. You should then click on the “Reauthenticate” link within the “Private Access” section and enter your credentials as usual.

 

Installing Zscaler Client Connector on a Mac

What to do if you encounter any problems

Please report services that you are unable to reach or any other problems that you encounter while using Unified Access to the ICT Service Desk.

If you encounter blocking issues and you can’t wait for the technical team to resolve them, then you can temporarily disable Unified Access and go back to your previous method of working.

  • To do this, open the Zscaler client connector and click on “Turn Off” in the private access section.
  • Please remember to go back in and turn it on when you have finished.

Accessing mapped network drives when using Unified Access

With Unified Access you will be able to access all your Imperial file shares and mapped drives directly from your device.

If after being enabled for Unified Access you are unable to access your mapped drives, it could be because of the following two reasons:

  1. Some people have drives mapped manually on their desktop computers and these need to be recreated manually on their laptop.
  2. Some drives have been mapped using the “short” name of the server (e.g. \\icfs5) rather than the “long” name (e.g. \\icfs5.cc.ic.ac.uk). Unified Access requires that all connections are made using the long name (also known as the Fully Qualified Domain Name or FQDN).

It should be possible for you to resolve both these problems yourself by following the below instructions.

Accessing mapped network drives when using Unified Access

Creating a mapped network drive in Windows

  1. Open Windows File Explorer by typing 'File Explorer' in the windows search bar next to the start button and then clicking on the file explorer app icon.
  2. Within file explorer, right click on 'This PC' and select 'Map network drive…'
  3. You can then select the drive letter that you would like to use and enter the full path to the folder, ensuring that you use the "long" (fully qualified) server name. For example, \\icfs5.cc.ic.ac.uk\FINANCE_sysaccws
  4. Make sure the 'Reconnect at sign-in' button is checked and press 'Finish'

If you need assistance, please contact the ICT Service Desk and they will be happy to help you.

Disconnecting a mapped drive

If you have a drive which is mapped to the short name of a server then this will first need to be disconnected so that you can create it with the correct name following the above instructions.

  1. Right click on the drive in 'File Explorer' and select 'Disconnect item'.
