SUSE / OpenSUSE
To configure PAM on SUSE you must modify four files, which control the various stages of authentication:
/etc/pam.d/common-account
/etc/pam.d/common-auth
/etc/pam.d/common-password
/etc/pam.d/common-session
important
By default these files are symlinks to their corresponding -pc
file, for example,
common-account -> common-account-pc
. If you directly edit these you are updating the inner
content of the -pc
file and it WILL be reset on a future upgrade. To prevent this you must first
copy the -pc
files. You can then edit the files safely.
# These steps must be taken as root
rm /etc/pam.d/common-account
rm /etc/pam.d/common-auth
rm /etc/pam.d/common-session
rm /etc/pam.d/common-password
cp /etc/pam.d/common-account-pc /etc/pam.d/common-account
cp /etc/pam.d/common-auth-pc /etc/pam.d/common-auth
cp /etc/pam.d/common-session-pc /etc/pam.d/common-session
cp /etc/pam.d/common-password-pc /etc/pam.d/common-password
NOTE: Unlike other PAM modules, Kanidm replaces the functionality of
pam_unix
and can authenticate local users securely.
The content should look like:
# /etc/pam.d/common-account
# Controls authorisation to this system (who may login)
account sufficient pam_kanidm.so ignore_unknown_user
account sufficient pam_unix.so
account required pam_deny.so
# /etc/pam.d/common-auth
# Controls authentication to this system (verification of credentials)
auth required pam_env.so
auth sufficient pam_kanidm.so ignore_unknown_user
auth sufficient pam_unix.so try_first_pass
auth required pam_deny.so
# /etc/pam.d/common-password
# Controls flow of what happens when a user invokes the passwd command. Currently does NOT
# push password changes back to kanidm
password required pam_unix.so nullok shadow try_first_pass
# /etc/pam.d/common-session
# Controls setup of the user session once a successful authentication and authorisation has
# occurred.
session optional pam_systemd.so
session required pam_limits.so
session optional pam_umask.so
session optional pam_kanidm.so
session optional pam_unix.so try_first_pass
session optional pam_env.so
warning
Ensure that pam_mkhomedir
or pam_oddjobd
are not present in any stage of your PAM
configuration, as they interfere with the correct operation of the Kanidm tasks daemon.
