SSO: Need an SP initiated SSO URL

[Shailendra Rajpoot]

Hi,

I have configured SAML SSO on both Atlassian and my IDP side.

Now I have to go to https://mydomain.atlassian.net, Atlassian's login page shows up, enter the user's email id, then It redirects me to IDP's login page based on the domain the user belongs to.

I can't have my users entering their email ID twice (on Atlassian login page and my Idp's login page, which is time consuming) when I have verified a domain and configured it as a federated domain.

I want an SP initiated URL, which forces users through go to my IDP's login page without asking to enter user's email id on Atlassian login page.

Can I have one?
