Comment 14 for bug 1083605

Added as:

$ tail /etc/pam.d/common-session
# /etc/login.defs and user settings, solving the problem of different
# umask settings with different shells, display managers, remote
sessions etc.
# See "man pam_umask".
session optional pam_umask.so
# and here are more per-package modules (the "Additional" block)
session required pam_unix.so
session [success=ok default=ignore] pam_ldap.so minimum_uid=1000
session optional pam_ck_connector.so nox11
# end of pam-auth-update config
session required pam_env.so
