Bug#778812: lightdm: Fails with large ladp user database

2015-02-20 Thread Massimo Barbieri
Package: lightdm
Version: 1.10.3-3
Severity: normal

Dear Maintainer,
I configured my Debian 8 to autenticate users over an openldap database server. 
The validation of the
credential has been done with libnss-ldapd libpam-ldapd ldap-utils nslcd. The 
ldap database contains 
many thousands of users. The problem is that lightdm hangs before loading the 
login screen with 99% of
CPU load and it seemes it try to download the complete list of the users.

Here are the log on the ldap server:

Feb 20 08:24:01 ldap5 slapd[6403]: conn=446978 fd=19 ACCEPT from

Many thanks for your work!
