At the moment, UserLogin is concentrating too much responsability:
1. Displays and manage a form intended for gathering login information;
2. Displays and manage a form intended for gathering information for a new account (create new account link)
3. Manages part of authentication process;
4. Coordinates creation of a new account.

From the 'object orientation' point of view, clearly UserLogin should be split on smaller components.
UserLogin, IMHO, should be *only* reponsible for
    1. Displays and manage a form intended for gathering login information;

Other tasks should be managed by their corresponding responsible classes.
In fact, it does not matter whether Mediawiki is object oriented or not. Object orientation is a very useful (and helpful!) concept which can be implemented even in bash scripts. Object orientation (or at least the concept) allows better organization of code, it's easy to maintain, easier to extend and easier to adjust to specific needs.

I've integrated LDAP authentication in our wiki and it was a nightmare :(
Now I'd like to replace LDAP by SAML and it's another nightmare, not working yet :(

Separating concerns on different classes would allow easier integration with several authentication layers.
* One thing is getting username/password/domain from a form.
* Another thing is using username/passoword for authenticating against a certain authentication layer.
* Another thing is obtaining data required for registration and coordinating the registration workflow.
* Another thing is performing the steps required to create a new account in a certain respository.

A good example which shows how integration is tangled can be seem at: https://ow.feide.no/simplesamlphp:mediawiki
and the corresponding 'plugin' provided by: https://ow.feide.no/_media/simplesamlphp:simplesamlphp-mw.php.zip?id=simplesamlphp%3Amediawiki&cache=cache

Thanks very much
