[SAC] We are one (with the LDAP)

[Howard Butler]

Thanks to hard work by Martin, and some fat-fingered operations by  
myself, upload.osgeo.org and download.osgeo.org now use OSGeo's LDAP  
to do their authentication business.

We still need to work out a script to shell-enable regular OSGeo LDAP  
users similar to ldap_create_user.py, but the list of users that we  
did have at the telascience LDAP has been migrated over.

Please let us know if you're having any trouble.  I will try to update  
our documentation on how to enable a blade to use this later today or  
tomorrow.
