I try to configure ADFS with gitlab to use SAML. My gitlab server have certificate signed by Active Directory.

From Internet Explorer, I can open this url "https://gitlab-adfs../users/auth/saml/metadata" without problem in TLS 1.2 (TLS 1.2, AES with 256 bit encryption (High); ECDH with 255 bit exchange).

When capture the exchange with tcpdump, I get :

Capture from gitlab - open url by Internet Explorer

When try to configure "Relying Party Trusts" from the same server, same url, I get

Capture from gitlab - open same url with adfs service

Of course, TLS1.0 is disabled and I get "could not create ssl/tls secure channel" error :

Error when try to open from adfs server

How to solve this issue ?

Best regards
