Configurable special login route for admins
**Is your feature request related to a problem? Please describe.**
When you only activate the external account to login on your org (sso) admins have no way of getting a login page and do not always want have access on the external account system.
**Describe the solution you'd like**
We implemented a custom route for admins /admin_sign_in for this purpose. We propose to add a config flag on the organization edit form to activate or deactivate it.
**Describe alternatives you've considered**
Not even bother to add a config flag in /system and just add it by default on Decidim.
**Does this issue could impact on users private data?**
