I've reassigned this to unity greeter. It seems reasonable for it to
assume usernames don't start with whitespace so they can be trimmed.
You can also find more information about authentication in
/var/log/lightdm/lightdm.log.

Title:
LightDM + LDAP accounts hang if username is preceded with whitespace
Status in nss_ldap:

Status in Unity Greeter:

Status in “unity-greeter” package in Ubuntu:
Triaged
Bug description:
This might affect PAM and/or nslcd instead, but lightdm should be able
to cope with it.
We have our users in an OpenLDAP directory, and I have disabled the
user list from lightdm. Some people seem to have the habit of waking
the monitor by pressing the spacebar, thus entering their username
with a preceding whitespace.
I have a line like this in syslog;
nslcd[2624]: [ac3ac4] username changed from " haneliuh" to "haneliuh"
The expected behaviour would be to just reject the login attempt and
return back to the login windows. Instead, lightdm now just hangs. If
one changes to a text console and back the lightdm login windows
remains all light grey.
