What I am looking for is the configuration of the MacOSX client. When I monitor with wireshark the only time I can see a pkinit AS_REQ is using the commandline: kinit -C KEYCHAIN: But only after I have already unlocked the PIV keychain. The MacOSX 10.9.5 or 10.10 systems have an /etc/krb5.conf that has the following pkinit configuration, under the realms stanza for both an MIT KDC and Windows KDC who are enabled for pkinit. Note you don't need the "krbtgt/realm@realm" in the KDC cert SAN if you set pkinit_require_krbtgt_otherName to false: pkinit_identities = KEYCHAIN: pkinit_anchors=FILE:/usr/local/kerberos/config/etc/pkinit/certificates/trusted-ca pkinit_require_crl_checking = false pkinit_kdc_hostname = Hostname_of_KDC pkinit_cert_match = &&<EKU>msScLogin,<KU>digitalSignature pkinit_cert_match = <SAN>.*@FEDIDCARD.GOV pkinit_require_krbtgt_otherName = false The problem is I never see pam_opendirectory or pam_krb5 make a Kerberos authentication call (AS_REQ) using the PKINIT preauth data (image below). After installing the smartcard services and doing the steps below, I can use the PIV for login and for screenlock, but no Kerberos calls take place. * security authorizationdb smartcard enable * Insert smartcard for USER * sc_auth accept -u USER –k PIV An Apple document talked about configuring /etc/cacloginconfig.plist, which I did, but no change. So I am curious if anyone has it working outside of using the kinit commandline?

I have had success with PK-INIT using a Windows KDC after building a proper SAN for the KDC cert. I am using attribute matching for SmartCard login.

I have not tried with an Open Directory server...

Has anyone got PKINIT working via OpenDirectory during login or via pam modules (pam_opendirectory or pam_krb5)?
Shame I don't see Apple publishing documents describing how to enable pkinit given federal government requirements for use of smartcards. Seems like its the users helping users, while Apple keeps quiet.
Appreciate any help.
