Hi team, I am trying to set up SASL/EXTERNAL binding mechanism. I perform all actions from our docs (Administration guide) First, I've set up SSL/TLS on the clean instance: 1) Cert was created and imported 2) Trusted CA cert was imported too 3) cert8.db, key3.db, secmod.db were copied to /etc/openldap/certs/ 4) Config was changed to accept SSL/TLS 5) Setup was tested and everything worked perfectly Then client certificate was created and approved by our CA. openssl x509 -in client_ds.crt -text Certificate: Data: Version: 1 (0x0) Serial Number: 16371655739931625967 (0xe333ce279b9c09ef) Signature Algorithm: sha256WithRSAEncryption Issuer: C=CZ, ST=Moravia, L=Brno, O=Default Company Ltd, OU=Dev, CN=Simon Validity Not Before: Feb 12 13:51:50 2016 GMT Not After : Oct 21 13:51:50 2029 GMT Subject: C=CZ, L=Default City, O=example.com, CN=simon pichugin/emailAddress=spichugi@xxxxxxxxxx After that certificate was imported to "userCertificate" attr of our user (I've cut the attr output): # spichugin, People, example.com dn: uid=spichugin,ou=People,dc=example,dc=com mail: spichugi@xxxxxxxxxx uid: spichugin givenName: simon objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetorgperson sn: pichugin cn: simon pichugin userPassword:: e1NTSEF9OVJhbUdER3prOE1JdENObnFJb3 userCertificate:: LS0tLS1CRUdJTiBDRVJUSUZJQ0FU Next, /etc/dirsrv/slapd-stal/certmap.conf was modified with this contents: certmap Example o=example.com Example:DNComps Example:FilterComps mail,cn Also tried with this: certmap Example cn=simon pichugin Example:DNComps Example:FilterComps mail,cn Also I have added "olcTLSVerifyClient: demand" to /etc/openldap/slapd.d/cn\=config.ldif /etc/openldap/ldap.conf contains only "TLS_CACERTDIR /etc/openldap/certs/", the rest options is by default Then I've tested setup with this command: [spichugi@rhel-ws ~]$ ldapsearch -H ldaps://rhel-ws.brq.redhat.com:636 -b "dc=example,dc=com" \ -Y EXTERNAL -U "dn:uid=spichugin,ou=People,dc=example,dc=com" -w Secret123 -d 1 ldap_url_parse_ext(ldaps://rhel-ws.brq.redhat.com:636) ldap_create ldap_url_parse_ext(ldaps://rhel-ws.brq.redhat.com:636/??base) ldap_sasl_interactive_bind: user selected: EXTERNAL ldap_int_sasl_bind: EXTERNAL ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP rhel-ws.brq.redhat.com:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying ::1 636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 attempting to connect: connect success TLS: certdb config: configDir='/etc/openldap/certs/' tokenDescription='ldap(0)' certPrefix='' keyPrefix='' flags=readOnly TLS: using moznss security dir /etc/openldap/certs/ prefix .
