Hello,

I'm having trouble adding etoken support to SSSD/openldap on a gentoo.

I have setup nssdb in /etc/pki/nssdb and add Safenet library to access etoken. I can successfully get the certificate in token with :

# /usr/libexec/sssd/p11_child --pre --nssdb=/etc/pki/CA/

Hi,

which version of SSSD are you using? I guess you've meant '--nssdb=/etc/pki/nssdb' in the example above?

now, to sssd itself ; I'm trying an ssh login, and the output on term is :

# ssh bar@example.com Please enter smart card

Please enter smart card

Please enter smart card

bar@example.com: Permission denied (publickey,keyboard-interactive).

With ssh everything is different, please check e.g. https://docs.pagure.org/SSSD.sssd/design_pages/smartcard_authentication_step... about how to use Smartcards with ssh. Typically the Smartcard reader is not attached to the host you want to authenticate to and as a result SSSD cannot handle the Smartcard authentication in this case.

I can see in p11_child.log that, it use nssdb to (successfully !) connect to the smartcard. I can see the correct label, the correct subject. The keyId is found (I don't understand why i need it and I'm not sure if the value i picked is right ?) Anyway, I get my uri, everything seem fine on this side.

Looking at sss_LDAP.log, i can see the request, everything look cool, i got :

sssd.dataprovider.pamHandler: Success

On the other side, in sss_pam.log i can see the same request but it end with :

[pam_dp_send_req_done] (0x0200): received: [28 (Module inconnu)][LDAP] (..)  [pam_eval_prompting_config] (0x4000): No prompting configuration found. (Thu Apr  2 15:23:08 2020) [sssd[pam]] [pam_reply] (0x0200): blen: 21 (Thu Apr  2 15:23:08 2020) [sssd[pam]] [pam_reply] (0x0200): Returning [28]: Module inconnu to the client (Thu Apr  2 15:23:08 2020) [sssd[pam]] [client_recv] (0x0200): Client disconnected!

I'm confused at how to understand this.

The sssd.conf is attached.

Thanks, Marc

[pam] pam_cert_auth = True pam_p11_allowed_services = +sddm, +sddm-helper, +kde, +sshd

Please do not 'sshd' here as mentioned above this would not work. For the first steps I would recommend to try to log in on a text console or try after logging in to the host where the Smartcard reader is connected to run 'su' or 'sudo'. I have not tested sddm or kdm, so I'm not sure if they should work out of the box.

Feel free to send the SSSD logs if Smartcard authentication with /bin/login, su or sudo still does not work.

HTH
