Created attachment 477596 [details] build.log openldap-2.4.45 does not build against (current ~amd64) libressl-2.5.4. This is not the same as bug 580888: openldap-2.4.44 does still build here. The errors are caused by changes to tls_o.c. That file now uses some new openssl functions, with backwards compatibility #defines (that fall back to code from openldap-2.4.44) behind OPENSSL_VERSION_NUMBER checks. libressl sets a high OPENSSL_VERSION_NUMBER (0x20000000L) but does not provide the functionality openldap expects. I don't know if there's a quick fix for this. Checking for the actual functionality provided by the ssl library from configure instead of using version checks would probably be the most robust fix, but if upstream is not interested in supporting LibreSSL they might not want to carry those checks. Full build.log attached.
