Hi, I am looking a olc config example for totp module. I like to try TOTP module. But I don't get it to work. Because I am not sure how to load it and set it up. Also I don't no what to except once it loaded. I using Ubuntu Wily 64-bit server which used on-line configuration (OLC). Compiled it from git. Used tag OPENLDAP_REL_ENG_2_4_42 and cherry-pick the totp directory from HEAD. ./configure --prefix=/usr/local/openldap --enable-overlays=yes --enable-ldap --enable-spasswd --enable-modules Also compiled the totp module in the directory self and installed. ls -al /usr/local/libexec/openldap -rw-r--r-- 1 root root 93234 Nov 13 22:51 pw-sha2.a -rw-r--r-- 1 root root 928 Nov 13 22:51 pw-sha2.la lrwxrwxrwx 1 root root 16 Nov 13 22:51 pw-sha2.so -> pw-sha2.so.0.0.0 lrwxrwxrwx 1 root root 16 Nov 13 22:51 pw-sha2.so.0 -> pw-sha2.so.0.0.0 -rwxr-xr-x 1 root root 72512 Nov 13 22:51 pw-sha2.so.0.0.0 -rw-r--r-- 1 root root 102352 Nov 13 22:50 pw-totp.a -rw-r--r-- 1 root root 928 Nov 13 22:50 pw-totp.la lrwxrwxrwx 1 root root 16 Nov 13 22:50 pw-totp.so -> pw-totp.so.0.0.0 lrwxrwxrwx 1 root root 16 Nov 13 22:50 pw-totp.so.0 -> pw-totp.so.0.0.0 -rwxr-xr-x 1 root root 69696 Nov 13 22:50 pw-totp.so.0.0.0 I modfied the config file /etc/ldap/slapd.d/cn\=config/cn\=module\{0\}.ldif. Which look like this. dn: cn=module{0} objectClass: olcModuleList cn: module{0} olcModulePath: /usr/lib/ldap olcModuleLoad: {0}back_hdb structuralObjectClass: olcModuleList entryUUID: 628d5926-2244-1034-90e2-d7e1d71167a8 creatorsName: cn=config createTimestamp: 20141227184617Z entryCSN: 20141227184617.050515Z#000000#000#000000 modifiersName: cn=config modifyTimestamp: 20141227184617Z dn: cn=module objectClass: olcModuleList cn: module olcModulePath: /usr/local/libexec/openldap olcModuleLoad: pw-totp dn: olcOverlay=totp,olcDatabase=hdb,cn=config olcOverlay: totp I can run it with /usr/local/openldap/libexec/slapd -u openldap -g openldap -F /etc/ldap/slapd.d -d config. Again I don't know what to expect if the modules is load. Who can help me futher. Greats, René van Dorst.
