ldap Nemesis module lets you integrate with the LDAP mechanism. This is a connection mechanism for directory databases - Microsoft Active Directory, for instance. Such directories are frequently used to keep track of personnel records. Being able to access LDAP data on your website, this guarantees an authentification process, meaning you’re using your true system of record for who has access. You may also use it to allow the website to provide a real-time picklist of valid employee names for a particular form.
