Provide a good MediaWiki Connector

Media Wiki does provide a Crowd connector, however, this connector doesn't use the Crowd APIs correctly.

On the first login attempt, it tries to create the user in its own database and then to create the user in Crowd's DB. If the user already exists in Crowd, the user is replaced by a user with the same username and its password is defaulted to a non-encrypted string (his user name).

So, the problems are:
1-) MediaWiki will always try to Create or Replace the Crowd user
2-) MediaWiki will default the password to a non-encrypted string (the user will never be able to login if the pwd is not changed).
3-) MediaWiki authentication will never work if the Application configuration in Crowd does not give Modify User permission for the Directory (MW does not handle the Not Permitted exception correctly).

The current workaround is:

1-) User logs to MediaWiki for the first time
2-) Admin go to the User Profile (in Crowd) and change his password
3-) User can login using the new password
