Lion Server: How to set up auto-accept for Lion Server Calendar Service

You can enable auto-accept for all Calendar service users by editing two configuration files using the instructions in this article.

1. Add the the following lines to the "Scheduling" section of the /etc/caldavd/caldavd.plist file:

    <key>Options</key>
    <dict>
    <key>AllowUserAutoAccept</key>
    <true/>
    </dict>

2. Edit the augments.xml file in the /Library/Server/Calendar and Contacts/Data/ directory. Note: If this file does not already exist on your server, create a Location or Resource in the iCal pane of Server app. That will create the augments.xml file.
3. For the "Default" record in that file, set the "<auto-schedule>" value to "true". This will globally affect all users. For example:

  <record>
    <uid>Default</uid>
    <enable>true</enable>
    <enable-calendar>true</enable-calendar>
    <enable-addressbook>true</enable-addressbook>
    <enable-login>true</enable-login>
    <auto-schedule>true</auto-schedule>
  </record>

4. Restart the Calendar Server in order for the changes to the plist and xml file to take effect.
