Need help tp setup saml auth

Hi,
I’ am looking for saml auth setup with taiga.
I don’t see local.py so i created one and added the config using git GitHub - jgiannuzzi/taiga-contrib-saml-auth: Taiga plugin for SAML authentication http://taiga.io
Can someone help me with the option and parameter which need to filled in config and what will be the ACS URl and Entity ID on saml settings (google).

Also I have tried ldap option but faced issue, whenever i change config to login via ldap in config.json and also updated conifg.py in taiga-back it does not allow me to login with normal account and not with ldap.
