Dear Maintainer,

I have a Debian 8 client that authenticate users over an open-ldap database. This has been done with libnss-ldapd libpam-ldapd nslcd. The users database is huge and includes thousands of users. The problem is that lightdm seems to try to download the complete lists of the users and it fails to load the login screen.

Here are the logs of the ldap server:

Do you use the userlist (greeter-hide-users=false in lightdm.conf)?

That looks like #722317 anyway.

Hi!
I do not use the users lists, and the option greeter-hide-users is
commented.
Thanks for your answer.
