4.8.2 Authentication Schemes
Daisy provides its own password authentication, but it is also possible to delegate the authentication to an external system. At the time of this writing, Daisy ships with support for authentication using LDAP and NTLM. It is possible to configure multiple authentication schemes and to have different users authenticated against different authentication schemes.
The authentication schemes are configured in the myconfig.xml file (which is located in <daisy-data-dir>/conf). Just search on "ldap" or "ntlm" and you'll see the appropriate sections. After making changes there, you will need to restart the repository server. To let users use the newly defined authentication scheme(s), you need to edit their settings via the user editor on the administration pages.
Daisy does not do automatic synchronisation of user information (such as updating the e-mail address based on what is stored in LDAP), but it is possible to auto-create users on first log in. This means that when a user logs in for the first time in Daisy, and does not yet exist in Daisy, an authentication scheme is given the possibility to create the user (if it exist in the external system). To enable this feature, search in the myconfig.xml file for "authenticationSchemeForUserCreation".
To debug authentication problems, look at the log files in <daisy-data-dir>/logs/daisy-request-errors-<date>.log. Problems in the configuration of the authentication schemes do not ripple through over the HTTP interface of the repository, thus are not visible in the Daisy Wiki.

For real samples, simply look at the source code of the NTLM and LDAP schemes. For this, download the Daisy source code, you'll find them in the following directories:
