Directory Services


The ldap_add_ext_s function initiates a synchronous add operation to a tree. For an add operation to succeed, the parent of the entry added must exist, or the parent must be empty (equal to the distinguished name of the root).

ULONG ldap_add_ext_s(
  LDAP* ld,
  PCHAR dn,
  LDAPMod* attrs[],
  PLDAPControl* ServerControls,
  PLDAPControl* ClientControls


[in] The session handle.
[in] A pointer to a null-terminated string that contains the distinguished name of the entry to add.
[in] An array of pointers to LDAPMod structures. Each structure specifies a single attribute. For more information, see the Remarks section.
[in] A list of LDAP server controls.
[in] A list of client controls.

Return Values

If the function succeeds, LDAP_SUCCESS is returned.

If the function fails, an error code is returned. For more information, see Return Values.


The parameters and effects of ldap_add_ext_s include those of ldap_add_s. The extended routine includes additional parameters to support client and server controls.

Before calling ldap_add_ext_s, create an entry by specifying its attributes in LDAPMod structures. Set the mod_op member of the each structure to LDAP_MOD_ADD, and set the mod_type and mod_vals members as appropriate for your entry.

Upon completion of the add operation, ldap_add_ext_s returns to the caller. Use ldap_add_ext if you prefer to have the operation completed asynchronously.

Multithreading: Calls to ldap_add_ext_s are thread-safe.

Note  When connecting to an LDAP 2 server, the application must perform a bind operation, by calling one of the ldap_bind or ldap_simple_bind routines, before attempting other operations.

ServerControls and ClientControls are optional and should be set to NULL if not used.
