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
