Re: (ITS#8364) [PATCH] back-meta idassert-bind tls_reqcert=never bug
by mohammad＠securiteam.io 01 Feb '16

Oh, thanks for clearing up the confusion, then is there anyway to prevent openldap from sending its server certificate as a client one when connecting to the meta target? I mean other than changing the TLSVerifyClient on the remote host as we don't have access to do this.

There is no bug here. The tls_reqcert setting controls whether the local node requires the remote target to provide a valid server certificate. It has nothing to do with client certificates at all. > Whenever openldap has a certificate/key either in > TLSCertificateFile/TLSCertificateKeyFile or in idassert-bind tls_cert/tls_key > settings, it completely ignores tls_reqcert in idassert-bd%d! Because the reqcert setting has nothing to do with this.

(ITS#8364) [PATCH] back-meta idassert-bind tls_reqcert=never bug
by mohammad＠securiteam.io 01 Feb '16

Full_Name: Mohammad Nweider Version: master OS: Redhat Linux URL: https://www.securiteam.io/contribs/openldap/mohammad-20160131-0001-fix-back… Submission from: (NULL) (89.100.154.148) Hello, We've found a small bug when trying to run openldap with meta backend, what we were trying to achieve is to have our server listens on ssl/tls port and to communicate with the meta targets over ssl/tls as well, but due to the fact that we're using a self-signed certificate and we don't have access to manage the meta targets, we wanted to skip the client certificate verification when connecting to the meta targets, so we tried adding idassert-bind tls_reqcert=never to our meta config for this purpose, but unfortunately it didn't work as expected. Whenever openldap has a certificate/key either in TLSCertificateFile/TLSCertificateKeyFile or in idassert-bind tls_cert/tls_key settings, it completely ignores tls_reqcert in idassert-bd%d! to reproduce you can just try to build your server with ssl/tls enabled, add the tls global/server settings: TLSCACertificateFile /usr/local/etc/openldap/cacert.pem TLSCertificateFile /usr/local/etc/openldap/servercrt.pem TLSCertificateKeyFile /usr/local/etc/openldap/serverkey.pem add some meta backend targets over ldaps with idassert-bind tls_reqcert=never: database meta suffix "dc=foo,dc=com" uri "ldaps://a.bar.com/dc=foo,dc=com" suffixmassage "dc=foo,dc=com" "dc=bar,dc=org" idassert-bind tls_reqcert=never Enable debugging and try to run some queries against your meta db. You will see a client certificate is sent to the meta target even with tls_reqcert=never! The mplelest fix I could come up with is to add the certificate/key to the ssl context only when is_server or lo->ldo_tls_require_cert is not zero like in the attached patch. Please let me know if I'm misunderstanding something or if this use case can be solved/achieved without this patch. Thanks,
