Mainly it wraps the OpenLDAP 2.x libs for that purpose.   Additionally the package contains modules for other LDAP-related stuff   (e.g. processing LDIF, LDAPURLs, LDAPv3 schema, LDAPv3 extended operations   and controls, etc.).\r\n\r\nSecurity Fix(es):\n\npython-ldap is a lightweight directory access protocol (LDAP) client API for Python. In versions prior to 3.4.5, ldap.dn.escape_dn_chars() escapes \\x00 incorrectly by emitting a backslash followed by a literal NUL byte instead of the RFC-4514 hex form \\00. Any application that uses this helper to construct DNs from untrusted input can be made to consistently fail before a request is sent to the LDAP server (e.g., AD), resulting in a client-side denial of service.
