Open-Xchange servlet for external login masks

Note: This document describes the new mechanism as introduced with 6.20. The is the old version.

Who should read this document

This document is written for web developers who would like to create a custom login mask for the Open-Xchange server. The login mask can reside on an external server i. e., not directly located in the domain of the Open-Xchange machines. It is also intended for administrators who install and maintain Open-Xchange services.


The Open-Xchange HTTP API has a function to create a session from external.

In order for this mechanism to work, you need to set com.openexchange.sessiond.autologin=true in /opt/open-xchange/etc/groupware/

Example form

A recent version of this sample can be found in the open-xchange package within the directory in /usr/share/doc.
