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
By default, the person must have registered with Friendica using the normal registration
procedures in order to have a Friendica user record, contact, and profile.
However, it's possible with an option to automate the creation of a Friendica basic account.
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
The configuration options for this module may be set in the .htconfig.php file
e.g.:
// ldap hostname server - required
$a->config['ldapauth']['ldap_server'] = 'host.example.com';
// dn to search users - required
$a->config['ldapauth']['ldap_searchdn'] = 'ou=users,dc=example,dc=com';
// attribute to find username - required
$a->config['ldapauth']['ldap_userattr'] = 'uid';
// admin dn - optional - only if ldap server dont have anonymous access

// admin password - optional - only if ldap server dont have anonymous access
$a->config['ldapauth']['ldap_bindpw'] = 'password';
// for create Friendica account if user exist in ldap
// required an email and a simple (beautiful) nickname on user ldap object
// active account creation - optional - default none
$a->config['ldapauth']['ldap_autocreateaccount'] = 'true';
