Comment 2 for bug 234473

The same happened to me in Intrepid, TWICE!
Im brazillian and i have what we know as Cyber Café (its like a place with pcs with internet access and food together, i dont know how to explain better...) and i use Ubuntu Intrepid with LTSP. I have 6 terminals plus the server. I created an html/javascript gui to add new users using the adduser command, creating at the same time a database with their infos and credits (to use the PCs). Every time when i reach about 350-400 users added, the list in users-admin becomes BLANK, and there is the only place where i can change the users password to unsafe words as they want (something like 123456, abcdefg, or wathever unsafe). Im adding them with a default password 123456 and then they use an script that i wrote that gives a gui to safely change the password using passwd, but some users want to use unsafe passwords, and the passwd doesn't allow it.

At Hardy i doesnt saw that blank-list bug, but i was with only about 250-300 users added. I only saw it when i upgraded to intrepid.

Sorry for the very bad english and sorry if i became confusing explaining my problem.
