Released 3.4.2 2022-07-06

This is a minor release to provide out-of-the-box compatibility with the merge
of libldap and libldap_r that happened with OpenLDAP's 2.5 release.

The following undocumented functions are deprecated and scheduled for removal:

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

The following deprecated option has been removed:

• OPT_X_TLS

Doc/

• SASL option usage has been clarified

Lib/

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

Modules/

• By default, compile against libldap, checking whether it provides a
  threadsafe implementation at runtime
• When decoding controls, the module can now distinguish between no value
  (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
  • OPT_X_TLS_ECNAME
  • OPT_X_TLS_PEERCERT
  • OPT_X_TLS_PROTOCOL-related options and constants

Fixes:

• Encoding/decoding of boolean controls has been corrected
• ldap.schema.models.Entry is now usable
• method keyword to ReconnectLDAPObject.bind_s is now usable
