Estou tentando configurar a montagem automática de diretórios base de usuários usando pam_mount e sshfs (os usuários são usuários LDAP na máquina remota).
Eu configurei pam_mount :
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE pam_mount SYSTEM "pam_mount.conf.xml.dtd">
<pam_mount>
<debug enable="1" />
<mntoptions allow="nosuid,nodev,loop,encryption,fsck,nonempty,allow_root,allow_other" />
<mntoptions require="nosuid,nodev" />
<logout wait="0" hup="0" term="0" kill="0" />
<mkmountpoint enable="1" remove="true" />
<volume fstype="fuse" path="sshfs#%(USER)@HOSTNAME:" mountpoint="~" ssh="1" options="reconnect,idmap=user,password_stdin,nonempty" />
</pam_mount>
Quando estou tentando su para o usuário, sou questionado sobre senha:
root@debian:~# su - pszubert

No HOST auth.log , há informações:

O que é estranho quando estou logado, posso montar o fs remoto usando sshfs pszubert@HOST: a/ .
O que há de errado?
Eu acho que o problema é com ~/.ssh na máquina local. O primeiro problema foi sobre known_hosts file, então criei global known_hosts in /etc/ssh/ssh_known_hosts . Agora ~/.ssh ainda é criado, mas está vazio mesmo se eu me conectar ao host remoto manualmente. Eu acho que se eu pudesse evitar de criação ~/.ssh resolveria problema. Existe uma maneira de desativá-lo?
