Dave/workspace/Google login urls
The following is a survey of Google login urls (because I couldn't find it documented). I'm trying to find the best way to point people to a particular service with a particular account, minimizing possible multi-account confusion.
There is no one answer, but here are some recommendations:
- https://drive.google.com/a/domain
- https://accounts.google.com/AccountChooser?continue=targetURL
accounts.gooogle.com
| url | Accounts logged in | notes | ||
|---|---|---|---|---|
| none | one | both | ||
| https://accounts.google.com/ServiceLogin | standard blank login | Password prompt (with option to "Sign in with a different account") | Password prompt, for account logged in longest | From any Google service, is the url forwarded to or provided by the "Sign in" button. | 
| https://accounts.google.com/AccountChooser | Forwards to "ServiceLogin" | "Choose an account" dialog, with account listed and "Add account" option | "Choose an account" dialog, with accounts listed and "Add account" option | Target of standard login page "Sign in with a different account" option | 
| https://accounts.google.com/AddSession | Forwards to "ServiceLogin" | standard blank login | standard blank login | Target of "Add account" option on standard "AccountChooser" page | 
To go to a particular Google service after loggin in, just add the "continue" parameter with a url encoded target url.
Google Apps
Can we gain usability be using Google App urls? Google App urls are often Google service urls with "/a/domain" after the domain (e.g. https://drive.google.com/a/example.org). What's a survey of those look like?
| url | Accounts logged in | ||
|---|---|---|---|
| none | other | both | |
| https://www.google.com/a/domain/ServiceLogin | Domain login | Domain login | Standard password prompt prepopulated with domain account (forwards to https://accounts.google.com/ServiceLogin?authuser=sessionNumber) | 
| https://www.google.com/a/domain/AccountChooser | Regular login | Regular AccountChooser Choosing a non-domain account does nothing (returns to original AccountChooser unchanged). Choosing "Add account" forwards to AddSession | Forwards to Admin for domain (UserHub) | 
| https://www.google.com/a/domain/AddSession | Regular login | Regular AccountChooser Choosing a non-domain account does nothing (returns to original AccountChooser unchanged). Choosing "Add account" forwards to AddSession | Forwards to Admin for domain (UserHub) | 
| https://admin.google.com/a/domain | Regular login | Regular AccountChooser | Admin for domain | 
| https://drive.google.com/a/domain | Domain login | Old style account chooser ( https://www.google.com/a/SelectSession) | Drive for domain | 
| https://groups.google.com/a/domain | Groups for domain (though not branded) | Groups for domain | Groups for domain, but with practically random account | 
The following don't work:
- www and naked forward to admin
- accounts forwards to Apps marketing page
