The main update that is present in the Banana release of GroupServer is a Facebook signup system. You can get Banana Split immediately.


Thanks to Steven Clift for his support for the Facebook signup system.

Facebook Signup

Previously, new members had to provide all their profile information during signup. Now new members have the option of logging into Facebook to retrieve the profile information. Signing up using Facebook is beneficial in two ways.

  1. The email address of the new member does not have to be verified, as Facebook has already verified the address. This reduces the number of steps required for sign-up from three to two.
  2. Much of the profile information does not have to be added, as it is copied in from Facebook.

The new member has a choice to use the older signup system that just uses email, or the new Facebook signup. The latter option is automatically available after the administrator has setup Facebook signup.


You must acquire two values from Facebook to enable Facebook Signup.

Application ID Value
This is the identifier for your Facebook application.
Application Secret Value
This is the secret key that is passed from your site to Facebook.

To get these values you will need to register your site as an application with Facebook. Do this by visiting <> and following the instructions. Facebook will then supply you with an App ID and App Secret. Once you have these you can carry out the following tasks.

  1. Log into the PostgreSQL database used GroupServer by using the following command:

    $ psql -Upgsql_user pgsql_dbname

    Note that pgsql_user and pgsql_dbname are the database user and database name that were set during installation. Both can be found in the instance.cfg file in the installation directory of GroupServer.

  2. Run the following SQL to add the App ID and App Secret to the options table:

    INSERT INTO option
    VALUES (
      App ID
    INSERT INTO option
    VALUES (
      App Secret

    Note the App ID and App Secret in the above SQL are the values provided by Facebook. Both values will need to be in quotes.

Once the data is in the options table the Sign Up page will automatically show the option to sign up using Facebook.
