PBKDF2 for OpenLDAP ======================= pw-pbkdf2.c provides PBKDF2 key derivation functions in OpenLDAP. Schemes: * {PBKDF2} - alias to {PBKDF2-SHA1} * {PBKDF2-SHA1} * {PBKDF2-SHA256} * {PBKDF2-SHA512} # Requirements * OpenSSL 1.0.0 or later # Installations First, You need to configure and build OpenLDAP. $ cd <OPENLDAP_BUILD_DIR>/contrib/slapd-modules/passwd/ $ git clone https://github.com/hamano/openldap-pbkdf2.git $ cd openldap-pbkdf2/ $ make # make install # Configration In slapd.conf: moduleload pw-pbkdf2.so You can also tell OpenLDAP to use the schemes when processing LDAP Password Modify Extended Operations, thanks to the password-hash option in slapd.conf. For example: password-hash {PBKDF2} or password-hash {PBKDF2-SHA256} or password-hash {PBKDF2-SHA512} # Testing You can get hash to use slappasswd. $ slappasswd -o module-load=pw-pbkdf2.la -h {PBKDF2} -s secret {PBKDF2}60000$Y6ZHtTTbeUgpIbIW0QDmDA$j/aU7jFKUSbH4UobNQDm9OEIwuw A quick way to test whether it's working is to customize the rootdn and rootpw in slapd.conf, eg: rootdn "cn=Manager,dc=example,dc=com" rootpw {PBKDF2}60000$Y6ZHtTTbeUgpIbIW0QDmDA$j/aU7jFKUSbH4UobNQDm9OEIwuw Then to test, run something like: $ ldapsearch -x -b "dc=example,dc=com" -D "cn=Manager,dc=example,dc=com" -w secret # Debugging You can specify -DSLAPD_PBKDF2_DEBUG flag for debugging. # Message Format {PBKDF2}<Iteration>$<Adapted Base64 Salt>$<Adapted Base64 DK> # References * [RFC 2898 Password-Based Cryptography][^1] [^1]: http://tools.ietf.org/html/rfc2898 * [PKCS #5 PBKDF2 Test Vectors][^2] [^2]: http://tools.ietf.org/html/draft-josefsson-pbkdf2-test-vectors-06 * [RFC 2307 Using LDAP as a Network Information Service][^3] [^3]: http://tools.ietf.org/html/rfc2307 * [Python Passlib][^4] [^4]: http://pythonhosted.org/passlib/ * [Adapted Base64 Encoding][^5] [^5]: http://pythonhosted.org/passlib/lib/passlib.utils.html#passlib.utils.ab64_encode # License This work is part of OpenLDAP Software <http://www.openldap.org/>.
