Note: If the remote gateway's certificate cannot be verified upon connection (because the root certificate is not included in the local keystore), an untrusted certificate warning appears. If a private certificate is installed on the remote gateway, the root certificate for the organization's certificate authority must be installed on the device in order to successfully access Citrix resources using Receiver for Mac. The device automatically recognizes commercially issued certificates (such as VeriSign and Thawte) provided the root certificate for the certificate authority exists in the local keystore. When securing remote connections using SSL, the mobile device verifies the authenticity of the remote gateway's SSL certificate against a local store of trusted root certificate authorities.
This is what's wrong:Ībout Secure Connections and SSL Certificates There is either an option to accept it or you'll have to get your Citrix administrator to fix this. It is supported in El Capitan.This means that the certificate that Citrix uses to create the SSL (Secure Socket Layer) connection is not known. Another newer even more secure option not listed above is IKEv2, this is supported already in iOS8 but is not supported in Yosemite and earlier on Macs. Note: PPTP is now considered to be particularly insecure due to its ancient design, L2TP is slightly better, and Cisco IPSec especially with the use of certificates rather than a pre-shared key is better still. So I currently since I have the choice and control over our systems where I now work use the built-in Cisco IPSec client with a Cisco IPSec compatible VPN server. This again can take days or weeks to happen. I have seen this happen numerous times with the result that hundreds of people in a corporate were completely locked out of the company VPN system and on one occasion this was for the best part of four days due to a weekend and bank holiday.Īlso using any VPN client other than the one Apple include is notorious for 'breaking' when Apple issue a new version of the operating system, until both the supplier updates their system to fix the issue, and your network manager gets around to updating your VPN Server to include that fix.

Of course while Java is disabled by Apple this means you either cannot install the SSL VPN settings and client, or the existing SSL VPN client itself is disabled. Java in a web-browser is one of the worst things to do as it makes your web-browser vulnerable to lots of malware and this will affect Macs as well as Windows, this issue particularly offends me, in fact this is why Apple periodically disable Java in OS X due to such security issues until a new patched version of Java is available. The process of automatically deploying an SSL setup by visiting a webpage requires your web-browser have Java support enabled. There are however plenty of negative ones as well.
Those are some of the positive aspects of an SSL VPN solution. In view of the above your network manager may not allow using anything other than SSL VPN even if your particular Cisco or Juniper appliance supports them.
