процедуры обработки опций LDAP (LDAP option handling routines)
Примечание (Note)
The LDAP libraries with the LDAP_OPT_REFERRALS option set to
LDAP_OPT_ON (default value) automatically follow referrals using
an anonymous bind. Application developers are encouraged to
either implement consistent referral chasing features, or
explicitly disable referral chasing by setting that option to
LDAP_OPT_OFF.
The protocol version used by the library defaults to LDAPv2 (now
historic), which corresponds to the LDAP_VERSION2 macro.
Application developers are encouraged to explicitly set
LDAP_OPT_PROTOCOL_VERSION to LDAPv3, using the LDAP_VERSION3
macro, or to allow users to select the protocol version.
