Up until fairly recently, the LTSP clients had no way of authenticating
using passphrase credentials. LTSP Thin clients merely logged into the
server, and LTSP Fat clients (and/or localapps) did some hacks to
configure the user and group information on the client, but stored no
authentication credentials.

If the the client is running LDM 2.2.14 or later, you should be able to
set LDM_PASSWORD_HASH=True in lts.conf, which stores a hash of the
passphrase used to log in and should allow pam to complete.

If you need a newer version of LDM and/or LTSP, There is a PPA that
includes newer versions of LTSP and related software:
