I have an LDAP setup also, with home directories over NFS, but no automounting or Kerberos. Like Heiko in post #2, killing gsettings from a tty helps. After that, Lightdm logs in properly.
This was on a fresh install of Ubuntu 11.10, I also moved folders like .compiz, .local, .config to a backup location before logging in the first time. Later I tried to copy the subdirectories for some applications back to their original location.
