◆ loginpage_idp_list()

auth_plugin_base::loginpage_idp_list ( $wantsurl )

inherited

Returns a list of potential IdPs that this authentication plugin supports.

This is used to provide links on the login page and the login block.

The parameter $wantsurl is typically used by the plugin to implement a return-url feature.

The returned value is expected to be a list of associative arrays with string keys:

url => (moodle_url|string) URL of the page to send the user to for authentication
name => (string) Human readable name of the IdP
iconurl => (moodle_url|string) URL of the icon representing the IdP (since Moodle 3.3)

For legacy reasons, pre-3.3 plugins can provide the icon via the key:

icon => (pix_icon) Icon representing the IdP

Parameters

string $wantsurl The relative url fragment the user wants to get to.

array List of associative arrays with keys url, name, iconurl|icon

Reimplemented in auth_oauth2\auth, auth_plugin_cas, auth_plugin_mnet, and auth_plugin_shibboleth.

◆ logoutpage_hook()

@global string

Reimplemented in auth_plugin_cas, auth_plugin_mnet, and auth_plugin_shibboleth.

◆ ntlmsso_finish()

auth_plugin_ldap::ntlmsso_finish ( )

Find the session set by ntlmsso_magic(), validate it and call authenticate_user_login() to authenticate the user through the auth machinery.

It is complemented by a similar check in user_login().

If it succeeds, it never returns.

◆ ntlmsso_magic()

auth_plugin_ldap::ntlmsso_magic ( $sesskey )

To be called from a page running under NTLM's "Integrated Windows Authentication".

If successful, it will set a special "cookie" (not an HTTP cookie!) in cache_flags under the $this->pluginconfig/ntlmsess "plugin" and return true. The "cookie" will be picked up by ntlmsso_finish() to complete the process.

On failure it will return false for the caller to display an appropriate error message (probably saying that Integrated Windows Auth isn't enabled!)

NOTE that this code will execute under the OS user credentials, so we MUST avoid dealing with files – such as session files. (The caller should define('NO_MOODLE_COOKIES', true) before including config.php)

◆ password_expire()

auth_plugin_ldap::password_expire ( $username )

Return number of days to user password expires.

If userpassword does not expire it should return 0. If password is already expired it should return negative value.

Parameters

◆ pre_loginpage_hook()

auth_plugin_base::pre_loginpage_hook ( )

inherited

Hook for overriding behaviour before going to the login page.

This method is called from require_login from potentially any page for all enabled auth plugins and gives each plugin a chance to redirect directly to an external login page, or to instantly login a user where possible.

If an auth plugin implements this hook, it must not rely on ONLY this hook in order to work, as there are many ways a user can browse directly to the standard login page. As a general rule in this case you should also implement the loginpage_hook as well.

◆ pre_user_login_hook()

auth_plugin_base::pre_user_login_hook ( & $user )

inherited

Pre user_login hook.

This method is called from authenticate_user_login() right after the user object is generated. This gives the auth plugins an option to make adjustments before the verification process starts.
