Hi there,
right now we're already using Drupal for our front page and newsletter management. But with the next site overhaul we may want to "expand" the use of drupal, by bridging it with our phpBB3 based forums. First tests with the "phpbbforum" module where quite promising.
However, at the moment we have a sub-domain based sectioning. example.com for the frontpage, forums.example.com for the forums, wiki.example.com for the wiki and so on...
In the next site revision, we want to introduce some listing for mods and maps, called "vault". So, since the vault would be something more special, we want to put it also into its own sub domain. Nothing special, with Drupals multi-site setup or using the "domain" module. But there is a problem, which really annoys me. The user management.
Due to the bridging, Drupal will get a special role about the user management. The users will only be able to edit their "Major" account data with the Drupal interface. But with a normal multi-site setup and a shared user-table, there would be many ways to get access to the account settings, or?
I mean, users could access/edit their informations on:
* example.com/user
* vault.example.com/user
