FortiClient VPN 7.0.0.0029 not working with SAML SSO in Linux

[techdsmart]

Hello,

I am deploying SAML SSO with Azure to our VPN. I having a challenge in Linux machines with FortiClient VPN 7.0.0.0029. When i enable SSO, i get a blank window/pop where i expect to authenticate with SSO (As attached).

The windows client is working well. Question: Does Linux version of FortiClient VPN 7.0.0.0029 support SAML SSO? Are there any extra packages required to be installed in the Linux machines? FYI, I am running this on Ubuntu 20.04.2 LTS

Well, thanks for help. Meanwhile I found that the issue is in REALM. When a realm is configured, the above problem appears. With default realm (= just /) the connection works.
