The reason that I see, could be that the user
postgre don't have a /home/postgres and when you execute the svn command at the libresource configuration/initialisation, the login/password are not kept for furthers command. So when LibreSource execute its commit, it do it as an unauthenticated user.
Seb
PS: LibreSource execute such command when creating a repository (I translate to similar cmd line)
