How to enable Single Sign-in Option

Hi Guruz,
I am using v7.3.5 (11f305f88a) open source version. can any one give me correct directions for the following questions
1.I need to know that does this version (or any of open source version) allow me to have single sign -in option?
2.I have configure LDAP successfully and test it. while login from my domain account can i bypass login page ? if yes then how ?

regards

you need to edit /etc/grafana/grafana.ini and modify the following

[auth.generic_oauth]
;enabled = false
;name = OAuth
;allow_sign_up = true
;client_id = some_id
;client_secret = some_secret
;scopes = user:email,read:org
;email_attribute_name = email:primary
;email_attribute_path =
;login_attribute_path =
;id_token_attribute_name =
;auth_url =
;token_url =
;api_url =
;allowed_domains =
;team_ids =
;allowed_organizations =
;role_attribute_path =
;tls_skip_verify_insecure = false
;tls_client_cert =
;tls_client_key =
;tls_client_ca =

can you please explain what should i write for these parameters like i dont know where from to pick client_id , sorry for my stupid questions !!! actually i am very new in grafana !
