Hi Taher, The reason we require a subdir is because we already have a system in place that works like this.
The user goes to https://reverseproxy and is presented with a login form where he enters his LDAP credentials. These are validated and the user is presented with a menu. The user clicks the links in the menu which takes him for example to https://reverseproxy/helpdesk or https://reverseproxy/monitoring or https://reverseproxy/files or https://reverseproxy/ofbiz (You get the idea) As the reverse proxy sends the users credentials, the user only enters them once for all applications and he is logged in automatically. The single point of login only works when we utilise subdirectories.
