[Dovecot] login_process_per_user I cant find this???

Hi All Just trying to config dovecot and I'm guessing there's been a change in the app.

In the dovecot.conf and on http://wiki.dovecot.org/MainConfig I see "Number of login processes to create. If login_process_per_user is yes, this is the number of extra processes waiting for users to log in." but as a config option I only see "login_process_per_connection = yes"

Has "login_process_per_user" been changed to "login_process_per_connection = yes"? Thanks Max
