cert options in ssl/tls connections
by Qiang Xu 28 Feb '12

28 Feb '12

Hello All, Today I came across a strange problem. I wrote a program to test ldap ssl/tls connection with OpenLDAP library. Something like the code snippet as follows: int ret = LDAP_OPT_SUCCESS; int cert_flag = LDAP_OPT_X_TLS_NEVER; ... ret = ldap_set_option(NULL, LDAP_OPT_X_TLS_REQUIRE_CERT, &cert_flag); if (ret != LDAP_OPT_SUCCESS) { fprintf(stderr, "unable to set require cert option (LDAP_OPT_X_TLS_REQUIRE_CERT): %s\n", ldap_err2string(ret)); } ... // bind to the server cert_flag = LDAP_OPT_X_TLS_DEMAND; ret = ldap_set_option(NULL, LDAP_OPT_X_TLS_REQUIRE_CERT, &cert_flag); if (ret != LDAP_OPT_SUCCESS) { fprintf(stderr, "unable to set require cert option (LDAP_OPT_X_TLS_REQUIRE_CERT): %s\n", ldap_err2string(ret)); } ... // bind to the server The first binding is successful, as expected. However, the second binding is also successful, which is contrary to my expectation, because I didn't create any cert file yet. Another observation here is that if the first binding with LDAP_OPT_X_TLS_NEVER is removed, and the second binding with LDAP_OPT_X_TLS_DEMAND set is done right from the beginning, then it will fail, as expected. So, it seems the first value set to the option LDAP_OPT_X_TLS_REQUIRE_CERT will override the later values, isn't it? Is it possible to change this option's value on the fly (means different bindings use different values for this cert option)? Thanks, Qiang

olcMirrorMode attribute in N-way multimaster
by Christopher Jones 28 Feb '12

28 Feb '12

Hi all, I'm working on an multimaster setup using the LDIF configuration (as opposed to slapd.conf). From my understanding of the documentation, Mirror Mode is distinct from N-way Multimaster in that it is an 'active-active/hot swap' configuration, and writes need to go a single server. In the admin guide's example found here: http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master the N-way multimaster has this attribute set: add: olcMirrorMode olcMirrorMode: TRUE Could someone clarify what the olcMirrorMode attribute is for in the N-way multimaster configuration? Thanks for your help in advance, Chris

slapd/slaptest fail with cyrus-sasl-2.1.25
by Markus Wernig 28 Feb '12

28 Feb '12

Hello all I have openldap-2.4.29 on x86 Solaris 11, compiled from source. It links against cyrus-sasl libraries, also compiled from source. All was working well with cyrus-sasl-2.1.23. After upgrading sasl to 2.1.25 slapd refuses to start: # /usr/local/libexec/slapd -d 8 4f4a8bad @(#) $OpenLDAP: slapd 2.4.29 (Feb 26 2012 19:45:45) $ @xfer-srv01:/opt/build.d/openldap-2/tmp/openldap-2.4.29/servers/slapd 4f4a8bad slap_sasl_init: auxprop add plugin failed 4f4a8bad slapd stopped. 4f4a8bad connections_destroy: nothing to destroy. If i downgrade cyrus-sasl again to 2.1.23, the error does not occur and slapd works normally without recompiling. I have seen bug reports about a similar problem with debian, and from that report (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=628237) it seemed that the problem lies with the sasl library, but should be fixed in the meantime. But still, I keep getting that error, and no configuration or compilation option (apart from totally disabling sasl) will help. Does anybody have an idea of how I could debug this further? Is this still a known issue? Thanks /markus

ok, thanks other question: i'm working on a lan with students, teachers, some guests and a pair of administrators. i need that everyone can authenticate himself on the lan. there are some computers in a room and i want they will be powered on will appear a display to log in. the same thing for every computer that will be connect to our local network. every user will have his permissions to visit different sites, to see server resources, etc. i don't know how prepare this but for the moment am preparing the server populating it with every user. Now i need to know one thing. with the my configuration idea, is it enough to have the Simple Binding inserting only the userPassword of Person objectClass? do i need also account and simpleSecurityObject classes?

Mozilla NSS -- how to deploy intermediate certificate
by Aaron Bennett 27 Feb '12

27 Feb '12

Hello, I need to publish the GeoTrust intermediate certificate; I'm using 2.4.29 built against Mozilla NSS. In OpenSSL world, I'd use -- I think -- TLSCACertificateFile /path/to/CA-certificates. Here's what I've tried: Download GeoTrust cert from https://knowledge.geotrust.com/support/knowledge-base/index?page=content&id… ; save as intermediate.crt Import with: # certutil -d /etc/openldap/nssdb/ -A -t ",," -n geotrust-intermediate -i intermediate.crt Certutil -L now shows: # certutil -d /etc/openldap/nssdb/ -L Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI geotrust-intermediate ,, ds.clarku.edu Pu,Pu,Pu cn=config looks like this: olcTLSCACertificateFile: geotrust-intermediate olcTLSCACertificatePath: /etc/openldap/nssdb olcTLSCertificateFile: ds.clarku.edu But still clients cannot verify the cert. Any Mozilla NSS guru's know what I'm going wrong? Thanks, Aaron
