Hello,
I created a PAM configuration with the goal to make it possible that a
user can either login by inserting a smartcard into a card reader and
entering the correct PIN, or by entering the traditional UNIX password.
This is what my /etc/pam.d/common-auth looks like:
#
# /etc/pam.d/common-auth - authentication settings common to all
services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See
# pam-auth-update(8) for details.
auth [success=2 default=ignore] pam_p11.so
/usr/local/lib/libcvP11.so
# here are the per-package modules (the "Primary" block)
auth [success=1 default=ignore] pam_unix.so nullok_secure
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one
already;
# this avoids us returning an error just because nothing sets a success
code
# since the modules above will each just jump around
auth required pam_permit.so
# and here are more per-package modules (the "Additional" block)
auth optional pam_group.so
auth optional pam_cap.so
# end of pam-auth-update config
This works nearly exactly as desired, "nearly" because though the login
with unix password works, the application shows "Login failed" for a
short time. Is there something I can change in the above file to avoid
this message?
Regards
Christoph
