The problem was in the software generating the installer. We have worked with their team and they have been very responsive. The problem has been fixed with the release of a new installer version (Less than one day, about 12 jours :-): Version: ejabberd-1.1.1_2-linux-installer.bin Download page: http://www.process-one.net/en/projects/ejabberd/download.html#binaries Note that the problem was not on ejabberd itself but on its installer generation tool, which is a third-party installer generator software.
