When logging in a LDAP user into kdm for the first time on a freshly
installed Roaming Workstation based on Debian Edu Jessie, the login went
fine but instead of being told that a local user was created, I was told
that the user had no home directory and the login failed.
These are the related messages in /var/log/auth.log:

Sep 4 19:33:17 thinkpadx200 systemd-logind[1735]: Removed session 1.
The new user is present in /etc/passwd and /etc/shadow, so I expect the
python script crashed when trying to send a message back to kdm, but it
could have happend earlier too. The mklocaluser.d/ fragment in place
seem to have executed as it should (~pere/.local/share/user-places.xbel
is correct).
syslog.syslog("Creating local home directory for user '%s'" % user)
# Copy content of /etc/skel
shutil.copytree("/etc/skel/.", newhomedir, True)
# Change perm of new home dir
os.chmod(newhomedir, dirmode)
chown_recursive(newhomedir, uid, gid)
# Flush nscd cache to get rid of original user entry
if os.access("/usr/sbin/nscd", os.X_OK):
runcmd(pamh, "/usr/sbin/nscd -i passwd")
# Hook for adjusting the freshly created home directory
# FIXME Should be rewritten in python, I guess
runcmd(pamh, "if [ -d /etc/mklocaluser.d ]; then ORIGHOMEDIR='%s'
USER='%s' /bin/run-parts /etc/mklocaluser.d ; fi" % (homedir, user))
# Let the user know what is going on
msg = pamh.Message(pamh.PAM_TEXT_INFO,
"Local user created in /home/, please log in again to
start using it.")
pamh.conversation(msg)
# Throw out user, as the log process cached the home directory
# and need to be restarted.
return pamh.PAM_TRY_AGAIN
No idea what could go wrong here.
