ZendTo is a web-based file transfer and collaboration system, primarily used for secure sharing of files, especially those containing sensitive or confidential data. It allows users to upload and share files with both internal and external recipients, and it is designed for ease of use and security. 

This configuration assumes your OpenLDAP directory uses memberof for automatic group management. As of OpenLDAP 2.5.18 and 2.6.8, an additional overlay, autogroup (general info article: Migration Strategy From slapodynlist) should also be added to your OpenLDAP configuration (this can be done dynamically on a server running those Release Levels or higher). 

If you are running OpenLDAP 2.4 or older releases of 2.5 and/or 2.6 we strongly recommend you upgrade to pick up all the other fixes and improvements along with this important new function.

If you are “manually” managing group membership then you would use a different authLDAPUsernameAttr value.

You setup https://zend.to/ for using LDAP by editing /opt/zendto/config/preferences.php. The relevant part for LDAP-settings is:

  'authenticator'         => 'LDAP',
  'authLDAPBaseDN'        => 'DC=example,DC=com',
  'authLDAPServers'       => array('ldap://ldap_server_ip:389'),
  'authLDAPAccountSuffix' => '@example.com',
  'authLDAPUseSSL'        => false,
  'authLDAPStartTLS'      => false,
  'authLDAPBindDn'        => 'uid=admin,ou=people,dc=example,dc=com',
  'authLDAPBindPass'      => 'your_password',
  'authLDAPUsernameAttr'  => 'uid',
  'authLDAPEmailAttr'     => 'mail',
  'authLDAPMemberKey'     => 'memberOf',
  'authLDAPMemberRole'    => 'cn=zendto,ou=groups,dc=example,dc=com',

Every user of the group zendto is allowed to login.
