I started getting the following message when going from Google Apps to Insightly, a third party application.
Currently this single sign-in feature is disabled for the domain kindlen.eu
The problem is not with the third party application.
It requires a setting to be adjusted by the domain administrator for the Google Apps domain.
Here is how to fix the issue.
If you have domain admin access rights for Google Apps you need to enable Federated Login by carrying out the following steps:
- From Google Apps, click "Manage this domain".
- In the blue bar, click on "Advanced tools".
- Under "Authentication", click "Federated Login using OpenID"
- Make sure the checkbox labelled "Allow users to sign in to third party websites using OpenID" is checked.
- Click "Save changes".
Please note: this does not give third party application any special access, or compromise the security of your account.
Federated Login is enabled by default for regular Google Apps domains, but for some reason Google turns it off for Premier accounts.
