Just LDAP auth, no other features. A minimalistic approach to auth when you need just auth and no other hassles with it.
- Editing PHP file for configuration? Really? Why not some form in Admin and save in the database?
Auth is a delicate matter, if fails, can lock your site
and force you to debug a live site to discover what happened
with your passwords and users.
Considering that auth is configured only once in an installation,
HTML forms and database querys are unnecessary overheads and hassles.
