/**
|
||||
* CLI: LDAP auth trace (plugin-accurate, without booting Joomla plugins)
|
||||
*
|
||||
* This script reads Joomla's "Authentication - LDAP" plugin parameters from #__extensions
|
||||
* and then performs the same login flow the plugin would:
|
||||
* - Connect → optional StartTLS → bind (service) → search user → bind as user with given password
|
||||
*
|
||||
* Usage:
|
||||
* php /var/www/html/cli/ldap-auth-trace.php --username <u> --password '<p>' [--json]
|
||||
*
|
||||
* Exit codes:
|
||||
* 0 = authentication SUCCESS
|
||||
* 1 = authentication FAILED (see messages)
|
||||
* 2 = usage error
|
||||
* 3 = LDAP plugin row not found / misconfigured
|
||||
* 4 = PHP ldap extension missing
|
||||
*
|
||||
* Notes:
|
||||
* - This bypasses Joomla plugin boot issues in CLI and gives precise LDAP errors.
|
||||
* - Honors LDAP plugin params + ENV overrides (same names as your role uses).
