By default, it will automatically log in with the hostname as the username and
password, which will typically be "ltspN" where N is a number based on the ip
address (i.e. with ip address range: 10.10.10.20 10.10.10.250, it'll be 20-250,
unless your netmask is something other than 255.255.255.0). So I typically set
up ltsp users for all the possible account names, and let LDM use the default
Username and Password.
The setup I use also doesn't actually use passwords at all:
You might consider using ssh keys instead of passwords, otherwise the users
could accidentally or maliciously change the password and lock the screen or
something. Configure to allow an alternate location for authorized ssh keys in
/etc/ssh/sshd_config (openssh-server 5.9+):
AuthorizedKeysFile %u/.ssh/authorized_keys
/var/lib/custom/authorized_keys/%u
Create the ssh key as root, which is what LDM uses to log in, be sure to use an
empty passphrase:
ltsp-chroot ssh-keygen
I prefer not to create homedirs for users who have never logged in, so I use
pam_mkhommedir. Edit /etc/pam.d/common-auth:
# automatically create new home directories as needed.
session required pam_mkhomedir.so silent
Then create the users, copy the keys into place, lock down the key files (edit
ARCH and TYPE at least):
pubkey=/opt/ltsp/ARCH/root/.ssh/id_TYPE.pub
auth_keys_dir=/var/lib/custom/authorized_keys/
for u in $(seq 20 250); do
u="ltsp${u}"
key=${auth_keys_dir}/${u}
adduser --disabled-password --no-create-home --gecos ,,, ${u}
cp ${pubkey} ${key}
chown root:${u} ${key}
chmod 0640 ${key}
done
There are many other details of things you *could* try, but that's the basic
configuration that's worked reasonably well for me.
