/**
|
|
* Friendica addon
|
|
*
|
|
* Module: LDAP Authenticate
|
|
*
|
|
* Authenticate a user against an LDAP directory
|
|
* Useful for Windows Active Directory and other LDAP-based organisations
|
|
* to maintain a single password across the organisation.
|
|
*
|
|
* Optionally authenticates only if a member of a given group in the directory.
|
|
*
|
|
* The person must have registered with Friendica using the normal registration
|
|
* procedures in order to have a Friendica user record, contact, and profile.
|
|
*
|
|
* Note when using with Windows Active Directory: you may need to set TLS_CACERT in your site
|
|
* ldap.conf file to the signing cert for your LDAP server.
|
|
*
|
|
* The required configuration options for this module may be set in the .htconfig.php file
|
|
* e.g.:
|
|
*
|
|
* $a->config['ldapauth']['ldap_server'] = 'host.example.com';
|
|
* ...etc.

|
