(ITS#8575) Argon2 Password hashing contrib module
by simon＠slevermann.de 26 Jan '17

26 Jan '17

Full_Name: Simon Levermann Version: OS: URL: ftp://ftp.openldap.org/incoming/simon-levermann-170126.patch Submission from: (NULL) (2001:638:708:f002:deab:9ae4:7f07:d350) This patch adds a password hashing module for the argon2 function to the contrib/slapd-modules/passwd/ modules. Argon2 is a relatively new hash function which has won the Password Hashing Competition (https://password-hashing.net) The attached patch file is derived from OpenLDAP Software. All of the modifications to OpenLDAP Software represented in the following patch(es) were developed by Simon Levermann simon(a)slevermann.de. I have not assigned rights and/or interest in this work to any party.

(ITS#8573) ldap* tools should be able to function w/o a conf file
by quanah＠openldap.org 23 Jan '17

23 Jan '17

Full_Name: Quanah Gibson-Mount Version: 2.4.44 OS: N/A URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.26) Right now, it is impossible to configure the ldap* command line tools so that they function in major circumstances w/o also having a configuration file (I.e., ldap.conf, .ldaprc, etc). For example, the ability to use startTLS with LDAP requires such a file so that the CA file and/or cert path for the tool can be defined. The "-o" option should be expanded to cover additional configuration parameters from the conf file, as has already been done with the network timeout parameter.

However, the ITS system is only for reporting bugs occuring in OpenLDAP as clearly noted on the ITS submission form. If you want to provide informational updates, they would probably best go to the openldap-technical mailing list.

(ITS#8572) FOR INFO ONLY: SASL SCRAM-SHA-1 authz may fail incorrectly
by william.b.clay＠acm.org 19 Jan '17

19 Jan '17

Full_Name: Bill Clay Version: 2.4.44 OS: Debian/GNU Linux 7.8 (Wheezy) URL: Submission from: (NULL) (79.12.44.250) Cyrus SASL 2.1.26 plugins/scram.c decode_saslname() may return a corrupt authz name. SASL SCRAM-SHA-1 auth with a "dn:" style authzID can return an authzID string with trailing original (escaped) characters appended. slapd may then incorrectly deny the requested proxy authorization because the returned value may fail match criteria that a correctly-decoded SASL name would pass. (There may be other SASL SCRAM scenarios in which this flaw would produce incorrect results.) Cyrus SASL issue: https://github.com/cyrusimap/cyrus-sasl/issues/416

(ITS#8571) Added a test for pcache + ldap backen with proxyauthz
by elecharny＠symas.com 18 Jan '17

18 Jan '17

Full_Name: Emmanuel L.charny Version: 2.4.45 OS: N/A URL: ftp://ftp.openldap.org/incoming/elecharny-20170118.patch Submission from: (NULL) (86.246.56.212) This patch adds a unit test for a server configured with proxycache and ldap backend, redirecting all the requests to a remote master server, which does not accept anonymous bind). The proxycache server caches searches and binds. The attached file is derived from OpenLDAP Software. All of the modifications to OpenLDAP Software represented in the following patch(es) were developed by Symas. Symas has not assigned rights and/or interest in this work to any party.

We went with something slightly different, but the rootdn requirement should be absolutely clear now.

Re: (ITS#8568) slapd SASL EXTERNAL bind getprop SSF bug; can provoke SEGFAULT

The slapd log of my same-host tests confirms they in fact used the IPv4 loopback address, 127.0.0.1, even though the bind URI specified the FQDN. > Not sure but the difference is the client IP address. If the client can reach > slapd through 127.0.0.1 the client's IP address is also 127.0.0.1 which could > make a difference in the SASL client handling. Anyone said hostname > canonicalization? Does setting sasl-host <fqdn> make a difference? The ~/.ldaprc used by the client in these tests contained "TLS_REQCERT none", so a mismatch between the server's FQDN and the peer address actually used would not have been detected. Another difference would be "ping-pong" memory allocation between client and server. Even though different processes, they may allocate from the same pool. With the client running on a different host in other tests, slapd would not be competing with other processes in a predictable, repeatable fashion (slapd SEGFAULTs were 100% repeatable for specific sequences of EXTERNAL binds, but only with client and server on the same host).
