Hi Ian, I found https://stathers.net/2016/01/14/thawte-premium-ssl- md5-gnutls.html but it would be surprising if that broke syncrepl but not ldapsearch. Still, worth checking if you haven't already. (ldapsearch and syncrepl are using the same CA certificate, right?)
Is there any interesting output if you run the consumer slapd at a higher debug level? Separate from slapd, are gnutls-serv/gnutls-cli able to communicate using the same certificates? ** Changed in: openldap (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openldap in Ubuntu. https://bugs.launchpad.net/bugs/1537762 Title: syncrepl does not work when using tls Status in openldap package in Ubuntu: Incomplete Bug description: syncrepl gives a "slap_client_connect: URI=ldap://ldaphost.domain.com Error, ldap_start_tls failed (-11)" error syncrepl was working perfectly until I upgraded libgnutls26 from version 2.12.14-5ubuntu3.10 to version 2.12.14-5ubuntu3.11 This new version of gnutls just seems to only have a simple fix for CVE-2015-7575 ldapsearch works perfectly happily with the new version of gnutls and our SSL certificate.
