Library VPN: Frequently Asked Questions and Troubleshooting

Ivanti Secure Access (previously Pulse Secure) is a free client application used to connect to the library’s Virtual Private Network (VPN). The library VPN establishes a secure connection between your computer or mobile device and the campus network.

You will need to install and use Ivanti Secure Access to access some UC Davis Library resources, including licensed materials, when you are off campus or on-campus but connected to a wi-fi connection other than UC Davis Eduroam (e.g., UCD Guest) or UCDH Prod on the health campus (e.g., UCDH Guest).

Once connected, you will have access to licensed library resources—those electronic materials, journal articles, library databases, streaming media services and other online tools that the library pays for on behalf of the university, but are not freely available to the public.

You need to connect to the library VPN if you are:

• Located off-campus
• On the Davis campus but connected to a wi-fi connection other than UC Davis Eduroam (e.g., UCD Guest)
• At UC Davis Health but connected to a wi-fi connection other than UCDH Prod (e.g., UCDH Guest)

If you are at UC Davis Health, the best option is to connect to UCDH Prod. 

No. Not all library resources require VPN. UC Library Search and other free resources are open to all and do not require use of the VPN.

Once connected, you will have access to licensed library resources—those electronic materials, journal articles, library databases, streaming media services and other online tools that the library pays for on behalf of the university, but are not freely available to the public.

Some vendors allow single sign-on; to access these materials, you can choose to use the Library VPN or sign into the vendor’s website using your UC Davis Kerberos (CAS) login and password instead.

To connect to the library VPN, you must first download and install the Ivanti Secure Access client on your computer or device. You only need to install Ivanti Secure Access once on each device you want to use to access library resources. Once installed and configured to connect to the library VPN, you will sign into Ivanti Secure Access using your UC Davis Kerberos (CAS) username and password.

The library VPN now requires Duo when connecting with Ivanti Secure Access. After entering your UC Davis Kerberos (CAS) username and password, a secondary prompt will appear asking for your Duo code or command.

Please use one of the following options:

• Push: Enter the word “push” and click Connect. You will receive a push notification to your Duo app that you must then approve. *This is the recommended method
• Phone: Enter the word “phone” and click Connect. Duo will call your registered phone number for authorization.
• Code: Enter your passcode from your Duo hard token or the Duo app and click Connect.

Note: For the “push” or “phone” options, if you wish to have Ivanti Secure Access use that method every time you connect, click the “save settings” box before clicking connect.

Due to differences in computer networks at UC Davis Health, the library offers other options for accessing library-licensed resources from the UC Davis Health campus or other affiliated clinical sites.

Ivanti Secure Access should work for the majority of faculty, staff, and students. Please refer to the Ivanti Secure Access installation instructions for your operating system and/or mobile device. Keep in mind that once you install Ivanti Secure Access, you will need to update it periodically, as you would with any software.

Yes, there is a Ivanti Secure Access client for Linux users. Please note, Linux is not an officially supported operating system. Users may try this client at their own risk.

Two package types are available for the two most used methods, rpm and deb:

• RPM for RedHat/CentOS 8 or higher (64bit)
• DEB for Ubuntu 20 or higher (64bit)

An icon for Ivanti Secure Access will be added to your applications menu. Launch the application and add a connection. Use “vpn.library.ucdavis.edu” as the URL setting. Once a connection is created, click connect and log in with your campus ID and passphrase.

Once Ivanti Secure Access is connected to the library VPN, you may use the browser of your choice to browse directly to your desired electronic resource, or you may browse databases.

Yes. You must sign into the library VPN using your UC Davis Kerberos (CAS) credentials every time you want to access licensed library resources from off campus.

On a Mac, you can find the Ivanti Secure Access icon at the top right of your display. On Windows, you can find the client by searching for Ivanti Secure Access in the Start menu. For easy access on Windows, we recommend pinning the Ivanti Secure Access client to your taskbar.

You must be on campus or use the library VPN to access many journal articles. Additionally, to access the full-text of articles you must customize the “Library Links” settings within Google Scholar. See Google Scholar tutorial video.

Yes, you may open multiple windows or multiple tabs. Either method works using Ivanti Secure Access.

Yes, once Ivanti Secure Access is connected to the library VPN, you may use your bookmarks normally.

“Failed to setup virtual adapter. (Error:1205).”

Go to your System Preferences and select Security & Privacy. On the “General” tab, look towards the bottom of the window for a message indicating that Ivanti Secure Access is being blocked. Click the “allow” button. You should now be able to log in with Ivanti Secure Access.

Mac OS 11 and lower.

Ivanti Secure requires Mac OS 12.6.6 or higher. We would highly recommend upgrading your Mac to at least 12.6.6 in order to use Ivanti. Please contact Apple support if you are unsure whether your Mac can be upgraded.

Windows 10 “Failed to setup virtual adapter. (Error:1205).”

Go to your Control Panel and open “Programs and Features”. Uninstall any listings with either “Juniper Networks” or “Pulse Secure” or “Ivanti” in the name. Reboot your computer and then download and install a new copy of the Ivanti Secure Access client from our library VPN page.

Ivanti Secure Access installation fails with Microsoft.VC80.CRT error.

Installation fails with message below or similar:

Please try the following:

1. Open command prompt window as admin and run the following command:
   fsutil resource setautoreset true C:\
2. Reboot system.
3. Open Services and ensure the following services are in a running state:
   • Windows Installer
   • Windows Management Instrumentation
4. Try Ivanti Secure Access installation again.

The Server or URL setting to use with Ivanti Secure Access for the library VPN is vpn.library.ucdavis.edu.

The library VPN uses your UC Davis Kerberos (CAS) username and password for authentication. If they are not working, then the campus service that the library VPN uses for authentication is not synced properly with your campus computing account and you will need to reset your passphrase.

Please visit UC Davis Knowledge Base for instructions on how to change your passphrase. Once reset, you should then be able to log into the library VPN.

The Library VPN only allows one session at a time per user. You will get this error if you are using Ivanti Secure Access on a mobile device and then try to connect with your laptop or desktop computer. You must disconnect the previous session first before starting the next session on your other device.

Closing Ivanti Secure Access without disconnecting first can also cause this error. Please ensure that you are disconnecting Ivanti Secure Access when you are done searching for articles/journals. To ensure Ivanti Secure Access has no lingering sessions or connections, please try completely exiting Ivanti and then relaunching it from your Start menu (Windows) or Applications folder (Mac), or by rebooting your computer.

Please note, any sessions will timeout after 15 minutes of idle use, or at a maximum session of four hours, so you should be able to log in at that time if this issue occurs.

Please see the options for connecting to the library VPN from UC Davis Health, including using Citrix.

Please restart your computer and try to connect Ivanti Secure Access to the library VPN again.

Try clearing your cache/cookies before starting the VPN client.

If you are running antivirus or Internet security software on your device, it may  conflict with Ivanti Secure Access. Temporarily disabling the software should allow Ivanti Secure Access to install/connect/work without issue. 

The library VPN is intended for access to electronic library resources only. Per UC Davis Cyber Safety policies, service ports on the library VPN have been restricted to web browsing and email only (access to campus services and networks remains unrestricted). Other Internet applications to external services, such as FTP or SSH, will not function until the library VPN is disconnected.

We recommend connecting to the library VPN when needing to access electronic library resources and then disconnect once your search is completed to limit disruption of your other Internet applications.

Some campus units have switched to using IPv6 for their network access. Please be aware that licensed resource vendors do not currently recognize UC Davis IPv6 networks for allowing access to electronic resources. 

If you are on an IPv6 network and cannot access an electronic resource, please try using the library VPN, until such time that the vendors can be notified and updated to allow UC Davis IPv6 networks. You can also choose to disable your IPv6 interface when needing to access licensed resources so that you are then using an IPv4 campus address.

Some vendors, such as IEEE, are using IPv6 for their networks. If you are also using IPv6, this can create a problem when attempting to access resources on that vendor’s site while using the library VPN. This is due to IPv6 taking precedence over IPv4, which is what the library VPN uses. So while the library VPN may be connected, your browser is opting to send traffic to the particular vendor site via IPv6 instead of IPv4, causing the vendor to think you are not on a valid UC Davis IP address and requesting that you sign in or pay for access. 

If you are having this issue, we have set up institutional logins with many of these vendors so that you can access the materials using your UC Davis kerberos account. Please see our Single Sign-On page for a list of vendors that support this.

If the vendor you are trying to access is not listed on the Single Sign-On page or you are still having an issue accessing resources, please submit a technical support request detailing your issue.
