No, I'm also using the webserver authentication.
May I ask why you think "password" auth is required ?

The elog has an internal userdatabase with longname, shortname, email etc.
Even if you are authenticated via the webserver, you also have to have an entry in that userdatabase.
This entry has to be created by the user who is allowed to get into elog by the webserver. 
Thus, the Self register option.
