**As** an OpenProject admin
**I want to** be able to configure SAML using a user interface
**so that** I don't have to use a command line and can see potential errors more easily.

Also: Due to the lack of a user interface it's currently impossible to configure SAML yourself unless you are self-hosting. In which case you have to do it by editing a yml file or using the rails console, both of which are not very user friendly ways of doing this.

**Acceptance criteria**

* a screen allowing the configuration of SAML under Administration -> Authentication Begin of the insertion-> SAML identity providersEnd of the insertion

* Begin of the insertionUse default common mapping schemes for user attributes

* Show the number of users connected to the authentication mode

* Allow metadata exchange to be filled using a URL or XML

* End of the insertion It should pre-fill new configurations with the most common options by default Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * allow pre-filling the options based on a given metadata URL Begin of the insertion


**Nice to have**

End of the insertion Begin of the deletion

End of the deletion * Begin of the insertionprovide a way to debug the authentication methodEnd of the insertion Begin of the deletion it should allow custom options (perhaps as json or yaml)End of the deletion

* Begin of the deletion it shouldEnd of the deletion show the most recent authentication attempts along with potential errors that occured during it (e.g. missing fields that have to be configured in the SAML server) Begin of the insertion
