==Setting the authentication method==
==Common Settings==
[[Image:authentication plugins.png|thumb|Choosing an authentication plugin, (only shows top of Authentication page)]]
To set the authentication method:
 
#Click on Authentication in the Site Administration block.
#On the authentication page, click on the closed eye icon to enable your chosen authentication plugin. In Moodle 1.8 onwards, you can choose to use more than one authentication method. Use the up/down arrow icons to arrange the plugins in order, with the plugin handling the most logins at the top of the page. This will minimise authentication server load.
#If you have chosen [[Email-based self-registration]], select "Email-based self-registration" from the self registration drop-down menu in the common settings section. Potential users will then be presented with a "Create new account" button on the login page.
#If you have courses with guest access, set the Guest login button to show.
#Click the "Save changes" button.
#Click on Settings opposite the authentication plugin(s) you have chosen.
#Configure the required settings and click the "Save changes" button.


==Multi-authentication==
===Self registration===
{{Moodle 1.8}}From Moodle 1.8 onwards, multi-authentication is supported. Simply click on the closed eye icon to enable a particular plugin.
registerauth
Default: Email-based self-registration
Choose which auth plugin will handle user self-registration.


Each authentication plugin may be used to find a username/password match. Once found, a user is logged in and alternative plugins are not used. Therefore the plugin which handles the most logins should be moved to the top of the page in order that less load is put on authentication servers.
===Guest login===
buttonguestloginbutton
Default: Show
You can hide or show the guest login button on the login page.


==Self registration==
===Alternate Login URL===
If you wish users to be able to create their own user accounts, i.e. self-register, then select Email-based self-registration from the drop-down menu.
alternateloginurl Default: Empty


==Guest login button==
If you enter a URL here, it will be used as the login page for this site. The page should contain a form which has the action property set to 'http://localhost/login/index.php' and return fields username and password. Be careful not to enter an incorrect URL as you may lock yourself out of this site. Leave this setting blank to use the default login page.


You can hide or show the guest login button on the login page. Hiding the guest login button disables [[Guest role|guest access]] to the Moodle site, however logged-in users can still enter any courses which allow guest access without being required to enrol.
===Forgotten password URL===
forgottenpasswordurl Default: Empty


==Alternate login URL==
If you enter a URL here, it will be used as the lost password recovery page for this site. This is intended for sites where passwords are handled entirely outside of Moodle. Leave this blank to use the default password recovery.
This should be used with care, since a mistake in the URL or on the actual login page can lock you out of your site. If you do mess it up, you can remove the entry from your database (table mdl_config) using, e.g., phpmyadmin for mysql.


==Forgotten password URL==
===Instructions===
{{Moodle 1.9}}If your lost password handling is performed entirely outside of Moodle (for example, only by a help desk), you can set the url of that service here. Anybody pressing a "lost password" link in Moodle will be redirected to this URL. Note that this will disable '''all''' of Moodle's lost password recovery options regardless of authentication method(s) in use.
auth_instructions Default: Empty


==ReCAPTCHA==
Here you can provide instructions for your users, so they know which username and password they should be using. The text you enter here will appear on the login page. If you leave this blank then no instructions will be printed.
[[Image:New account form with captcha element.png|thumb|New account form with CAPTCHA element]]
A CAPTCHA is a program that can tell whether its user is a human or a computer. CAPTCHAs are used by many websites to prevent abuse from bots, or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.


{{Moodle 1.9}}From Moodle 1.9.1 onwards, spam protection may be added to the [[Email-based self-registration]] new account form with a CAPTCHA element - a challenge-response test used to determine whether the user is human.
===Allowed email===
domainsallowemailaddresses  Default: Empty


ReCAPTCHA keys can be obtained from http://recaptcha.net by [https://admin.recaptcha.net/accounts/signup/?next= signing up for an account] (free) then entering a domain. The public and private keys provided can then be copied and pasted into the ''recaptchapublickey'' and ''recaptchaprivatekey'' fields in the manage authentication common settings, and the changes saved.
If you want to restrict all new email addresses to particular domains, then list them here separated by spaces. All other domains will be rejected. eg ourcollege.edu.au .gov.au


In addition to setting reCAPTCHA keys, email-based self-registration should be set as the self registration authentication plugin in the manage authentication common settings and the reCAPTCHA element should be enabled in the [[Email-based self-registration]] settings.
===Denied email===
domainsdenyemailaddresses  Default: Empty


==Locking profile fields==
To deny email addresses from particular domains list them here in the same way. All other domains will be accepted. eg hotmail.com yahoo.co.uk
To prevent users from altering some fields (e.g. students changing profile information to inappropriate or misleading information), the site administrator can lock profile fields.


[[Image:Authent-data-map-fname.jpg|Data Mapping Options]]
*These fields are optional. You can choose to pre-fill some Moodle user fields with information from the LDAP fields that you specify here.  If you leave these fields blank, then nothing will be transferred from LDAP and Moodle defaults will be used instead.  In either case, the user will be able to edit all of these fields after they log in.
*'''Update local''': If enabled, the field will be updated (from external auth) every time the user logs in or there is a user synchronization. Fields set to update locally should be locked.
*'''Lock value''': If enabled, will prevent Moodle users and admins from editing the field directly. Use this option if you are maintaining this data in the external auth system.
*'''Update external''': If enabled, the external auth will be updated when the user record is updated. Fields should be unlocked to allow edits.  Note: Updating external LDAP data requires that you set '''binddn''' and '''bindpw''' to a bind-user with editing privileges to all the user records. It currently does not preserve multi-valued attributes, and will remove extra values on update.


If you are using a mixture of authentication types (such as IMAP and manual), then the fields you lock in the authentication options will only apply to the type of authentication indicated by the drop down box at the top of the screen.  Remember to test the field locking by logging in with the proper type of account!  If you test with a manual account but have set the field locking to apply to IMAP accounts, you will not be able to tell if it worked!
