Setup Google Apps accounts with SAML authentication

Some Google Apps domain require SAML authentication instead of the Google authentication.

To enable SAML authentication, follow the following steps:

1. Open Terminal

2. The the following line and press ENTER:

   defaults write com.mailplaneapp.Mailplane SAMLAccounts "your@email-address.com"

   If you have more than account to set, separate them with a comma: defaults write com.mailplaneapp.Mailplane SAMLAccounts "first@email.com,second@email.com"

3. Restart Mailplane to apply the setting

Limitations: There is no automatic sign-in for the accounts listed in SAMLAccounts and you won't get new email notifications.
