Public bug reported:

Hello,

I run ubuntu in an enterprise environment, and it requires that we have
2800+ users in /etc/passwd.

The problem that I'm seeing, is that the login window hangs for 3-5
minutes after entering a username into the 'username' field. While it's
hung, you can see that the accounts-daemon seems to be looping through
users in /etc/passwd (you see a new accounts-daemon process spawn as
each user and run for a small amount of time). In previous versions of
ubuntu, I've been able to work around this by enabling the manual login
field (i.e. the username/password field instead of a dropdown with
users).

However, in 13.10, this hang occurs even with the manual
username/password field, and the 3-5 minute delay between entering the
username, and being able to type your password is making things
unusable. Is there a way I can prevent the accounts daemon from doing
this? Since our home folders are on network file servers, I'm worried
about the load that this might be causing there (I'm seeing some
indication that the accounts-daemon is going to look through each home
folder for a ~/.profile, or something similar)

Please let me know if there's any other information I can provide:

Ubuntu Release: 13.10 (linux 3.11.0-12-generic)
Lightdm Version 1.8.2-0ubuntu1
