[SAC] Re-enable LDAP user creation

[Sandro Santilli]

The OSGeo Userid creation form is still offline:
https://www.osgeo.org/cgi-bin/ldap_create_user.py

It mentions being "under maintenance".
I guess it would be pretty frustrating for new users
to be left like that, with nothing to do.

How about adding at least an email address to send a registration
request to ?

I understand the "maintenance" is the work that adds
email-confirmation, but there's no progress update on
the ticket since 4 days: https://trac.osgeo.org/osgeo/ticket/1665
Frank: is that going to happen ? How long will it take ?
