[389-users] Problem with plugin

[Juan Asensio Sánchez]

Hi

We have done a plugin that dynamically change some attributes of the
search results. The main code is like this:


int smbhack_hook( Slapi_PBlock* pb ) {
	// ...
	Slapi_Entry** s_entradas = NULL;
	Slapi_PBlock* pbi = NULL;

	// ...
	rv = slapi_pblock_get(
		pb,
		SLAPI_SEARCH_STRFILTER,
		&s_strfilter
	);
	if (rv == -1) {
		slapi_unlock_mutex(cfg_lock);
		return LDAP_OP_IGNORED;
	}

	// ...
	slapi_search_internal_set_pb(
		pbi,
		s_dn,                      // Base
		s_scope,                   // Ambito
		s_strfilter,               // Filtro
		s_attrs,                   // Atributos buscados
		s_attrsonly,               // Flag de seleccion
		s_controls,                // Controls
		s_uid,                     // DN vs uid
		plugin_id,                 // ComponentId
		SLAPI_OP_FLAG_NEVER_CHAIN  // Flags
		);

	// ...
	rv = slapi_pblock_get(
		pbi,
		SLAPI_PLUGIN_INTOP_SEARCH_ENTRIES,
		&s_entradas
	);

	// ...
	if (s_entradas == NULL || s_entradas[0] == NULL) {
		slapi_unlock_mutex(cfg_lock);
		destruir_estructura_dn(pila_dn_invocador);
		slapi_pblock_destroy(pbi);
		return LDAP_OP_IGNORED;
	}

	// ...
}

The problem is thar when doing a search with this filter:

(&(ou:dn:=People)(uid=myuid)(objectClass=sambaSamAccount))

the method slapi_pblock_getfor the attribute
SLAPI_PLUGIN_INTOP_SEARCH_ENTRIES returns s_entradas != null, but if I
do a search with this filter:

(&(|(ou:dn:=Computers)(ou:dn:=People))(uid=myuid)(objectClass=sambaSamAccount))

s_entradas is null or s_entradas[0] is null and the operation is ignored.

What could the reason?

If anyone can be useful, this plugin simulates a samba domain trust,
making some users of other organization in a group, change dinamycally
their sambasid to make them a valid user in the target windows domain.
