[SAML-Git BASH]Cannot use SAML Account to authenticate private gitlab account

Hi everyone,

I am finding way to use git bash (tortoisegit) to push, clone, commit repository from private gitlab by using SAML account with IDP Okta, but there is no document or reference of gitlab. There is a post of github.com told that we only use personal access token to authenticate Git bash action. Does we have any similar document of gitlab talk about that, because our customer are using gitlab and I need proven to convince them. Thank you

This is document of GitHub about using SAML Account in git bash to authenticate https://help.github.com/en/articles/about-authentication-with-saml-single-sign-on

For example 1.Clone a project from my private Gitlab

2.TortoiseGit ask for password but because this is a SAML Account, so I don't know what it is

3. I try to enter the password of Account on IDP Okta and of course it didn't worked
