ldap.h includes this as well:
#if LDAP_DEPRECATED
LDAP_F( LDAP * )
ldap_init LDAP_P(( /* deprecated, use ldap_create or ldap_initialize */
LDAP_CONST char *host,
int port ));
LDAP_F( LDAP * )
ldap_open LDAP_P(( /* deprecated, use ldap_create or ldap_initialize */
LDAP_CONST char *host,
int port ));
#endif
Apps such as dovecot and apr-1 have,
#define LDAP_DEPRECATED 1
