I'm trying to configure automounting of users home directories using pam_mount and sshfs (users are LDAP users on remote machine).
I configured 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>
When I'm trying to su to user I'm asked about password:
root@debian:~# su - pszubert
pam_mount(pam_mount.c:553): pam_mount 2.5: entering session stage
reenter password for pam_mount:

In HOST auth.log there is info:

What is weird when I'm logged in I can mount remote fs using sshfs pszubert@HOST: a/.
What's wrong?
I think that problem is with ~/.ssh on local machine. First problem was about known_hosts file, so I created global known_hosts in /etc/ssh/ssh_known_hosts. Now ~/.ssh is still created, but is empty even if I connect to remote host manually. I think that if I could prevent of creation ~/.ssh it would solve problem. Is there a way to disable it?
