Suggestion for Multi User Image Gallery

[Ow Mun Heng]

I'm looking around for a PHP/MySQL (or just directory based) image
gallery which can accomodate a couple of users. 

It would be best if the gallery can use LDAP for login authentication.

Most importantly, it must be able to be used by multiple users, with
web-based upload.

I've looked at 
singapre <- I think this is for 1 user only
(http://singapore.sourceforge.net/?page=demo)
4images - Commercial
(http://www.4homepages.de/)
gallery <--This looks nice
(http://gallery.menalto.com/index.php)
PhotoPost Pro <- Commercial
(http://www.photopost.com/photopost)

Can anyone provide some suggestions?
