Author: OrbisAI Security <[email protected]> Committer: Daniel-Constantin Mierla <[email protected]> Date: 2026-06-12T14:37:42+02:00 ldap: escape NUL byte per RFC 4515 in ldap_rfc4515_escape Add missing '\0' -> '\00' escape case to ldap_rfc4515_escape() for RFC 4515 ç2.4 compliance. NUL is one of five characters RFC 4515 requires to be escaped in filter assertion values; the other four (*, (, ), \) were already handled.
