This bug is indeed still present in Lucid. With an account only present in LDAP and the default common-password configuration, I get the following when trying to change the password for the user stored in LDAP:
$ sudo passwd testing
passwd: Authentication information cannot be recovered
passwd: password unchanged
Removing only the use_authtok parameter, I get the following:
$ sudo passwd testing
New password:
Re-enter new password:
LDAP password information changed for testing
passwd: password updated successfully
