I saw that we have the LDAP option to import users with/without TOKEN to answer a survey. I will like to import all these users with their own TOKEN from another DB.

So far I know, when I clicked the LDAP option these files are involve:

Path: application/config/
File: LDAP.php
Desc: Server configuration and set of queries.

Path: application/helpers/
File: LDAP_helper.php
Desc: Get the connections and start queries.

Path: application/views/admin/token/
File: ldapform.php
Desc: Is the form that we see on the browser with the available queries to execute..

Path: application/controllers/admin/
File: tokens.php
Desc: Use the info from all previous files to finish the queries and import the info to generate the access tokens to answer the survey.

I will like to be oriented so I can modify/create the code using the right structure, so this option could be available for other users.
