* Class SAMLAuthenticator |

22

* |
|
23
|
|
|
* Authenticates the user against a SAML IdP via a single sign-on process. |
|
24
|
|
|
* It will create a {@link Member} stub record with rudimentary fields (see {@link SAMLController::acs()}) |
|
25
|
|
|
* if the Member record was not found. |
|
26
|
|
|
* |
|
27

|
* You can either use: |
|
28
|
|
|
* - just SAMLAuthenticator (which will trigger LDAP sync anyway, via LDAPMemberExtension::memberLoggedIn) |
|
29
|
|
|
* - just LDAPAuthenticator (syncs explicitly, but no single sign-on via IdP done) |
|
30
|
|
|
* - both, so people have multiple tabbed options in the login form. |
|
31
|
|
|
* |
|
32
|
|
|
* Both authenticators understand and collaborate through the GUID field on the Member. |
