Released 3.4.2 2022-07-06

This is a minor release to provide out-of-the-box compatibility with the merge

  • ldap.cidict.strlist_minus

  • OPT_X_TLS

Doc/

Lib/

  • ppolicy control definition has been updated to match Behera draft 11

Modules/

  • By default, compile against libldap, checking whether it provides a

    (now exposed as None) and an empty value (exposed as b'')
  • Several new OpenLDAP options are now supported:
    • OPT_SOCKET_BIND_ADDRESSES
    • OPT_TCP_USER_TIMEOUT
    • OPT_X_SASL_MAXBUFSIZE
    • OPT_X_SASL_SECPROPS

This release requires Python 3.6 or above,
and is tested with Python 3.6 to 3.10.
Python 2 is no longer supported.

New code in the python-ldap project is available under the MIT licence
(available in LICENCE.MIT in the source). Several contributors have agreed
to apply this licence their previous contributions as well.
See the README for details.

The following undocumented functions are deprecated and scheduled for removal:

  • ldap.cidict.strlist_intersection
  • ldap.cidict.strlist_minus
  • ldap.cidict.strlist_union

Security fixes:

  • Fix inefficient regular expression which allows denial-of-service attacks
    when parsing specially-crafted LDAP schema.
    (GHSL-2021-117)

Changes:

  • On MacOS, remove option to make LDAP connections from a file descriptor
    when built with the system libldap (which lacks the underlying function,
    ldap_init_fd)
  • Attribute values of the post read control are now bytes
    instead of ISO8859-1 decoded str
  • LDAPUrl now treats urlscheme as case-insensitive
  • Several OpenLDAP options are now supported:
    • OPT_X_TLS_REQUIRE_SAN
    • OPT_X_SASL_SSF_EXTERNAL
    • OPT_X_TLS_PEERCERT

Fixes:

  • The copy() method of cidict was added back. It was unintentionally
    removed in 3.3.0
  • Fixed getting/setting SASL options on big endian platforms
  • Unknown LDAP result code are now converted to LDAPexception,
    rather than raising a SystemError.

slapdtest:

  • Show stderr of slapd -Ttest
  • SlapdObject uses directory-based configuration of slapd
  • SlapdObject startup is now faster

Infrastructure:

  • CI now runs on GitHub Actions rather than Travis CI.

Released 3.1.0 2018-05-25

This release brings two minor API changes:

  • Long-deprecated functions ldap.open() and ldap.init() are removed
  • LDAPObject.compare_s() and compare_ext_s return bool instead of 0 or 1

All changes since 3.0.0:

  • Fail if pyasn1 is not installed
  • Fix parsing of PPolicyControl ASN.1 structure
  • Use items() when appropriate in dict iteration
  • Add support for tracing LDAP calls. Tracing can now be enabled with
    the env var PYTHON_LDAP_TRACE_LEVEL and redirected to a file with
    PYTHON_LDAP_TRACE_FILE.
    (This is mainly intended for debugging and internal testing; the
    configuration or output may change in future versions.)
