Typedef Documentation

sync_config_t

typedef struct sync_config_s sync_config_t

Definition at line 1 of file proto_ldap_sync.h.

sync_init_t

typedef int(* sync_init_t) (fr_ldap_connection_t *conn, size_t sync_no, proto_ldap_sync_t const *inst, uint8_t const *cookie)

Allocate and initialise a sync query.

Called at the start of the sync operation, after any cookie has been retrieved.

Sends the persistent search query to the LDAP server with the appropriate controls for type of directory in use.

Parameters

[in]	conn	to initialise the sync on
[in]	sync_no	number of the sync in the array of configs.
[in]	inst	instance of ldap_sync this query relates to
[in]	cookie	to send with the query (RFC 4533 only)

Returns

• 0 on success.
• -1 on error.

Definition at line 95 of file proto_ldap_sync.h.

sync_msg_t

typedef int(* sync_msg_t) (sync_state_t *sync, LDAPMessage *msg, LDAPControl **ctrls)

Received an LDAP message related to a sync.

Called whenever the server returns a message, during any phase of the sync.

This function is responsible for freeing the LDAP message.

Parameters

[in]	sync	we received the message for.
[in]	msg	the LDAP message received.
[in]	ctrls	received with the message.

Returns

• 0 on success.
• -1 on error.

sync_state_t

typedef struct sync_state_s sync_state_t

Definition at line 1 of file proto_ldap_sync.h.

Enumeration Type Documentation

sync_op_t

enum sync_op_t

Operations to perform on entries.

Enumerator
SYNC_OP_INVALID	Invalid sync operation.
SYNC_OP_PRESENT	Entry is present and unchanged on the server.
SYNC_OP_ADD	Entry should be added to our copy.
SYNC_OP_MODIFY	Entry should be updated in our copy.
SYNC_OP_DELETE	Entry should be deleted from our copy.

Definition at line 70 of file proto_ldap_sync.h.

Function Documentation

ldap_sync_conf_attr_add()

int ldap_sync_conf_attr_add	(	sync_config_t *	config,
		char const *	attr
	)

Check if an attribute is in the config list and add if not present.

Parameters

[in,out]	config	to check for attribute.
[in]	attr	to look for.

Returns

• 1 if attr is added
• 0 if attr was already present
