          Issue ID: 10326
           Summary: SNI passing requirements differ across TLS
                    implementations
           Product: OpenLDAP
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: needs_review
          Severity: normal
          Priority: ---
         Component: libraries
          Assignee: [email protected]

  Target Milestone: ---

mbedtls 3.6.3 has changed behaviour to correct a long standing issue where not
setting a hostname meant hostname checking was disabled completely
(CVE-2025-27809).

It seems that how we do SNI vs. basic certificate checking differs between TLS
implementations and our logic in ldap_int_tls_connect and ti_session_connect.

This is also the reason test067-tls started failing on mbedtls builds.
