<LDAP session>: Character string (with quotes)

Name of LDAP session used.

<Object DN>: Character string (with quotes)

<Attribute name>: Character string (with quotes)

Remarks

LDAP server and local LDAP object

The LDAP server contains LDAP objects.

The local LDAP object is an LDAP object fetched from the server.

Updating the local LDAP object

When a read LDAP function is run (LDAPListAttribute, LDAPNbValue, LDAPValue), the server object is entirely fetched back in order to limit the communications with the server. Therefore, if these read functions are called several times with the same DN, the communication with the server is established by the first call. The other calls will read the local object.

LDAPNbValue does not update the local LDAP object if the DN passed in parameter is identical to the last DN passed in parameter to one of the following functions: LDAPListAttribute, LDAPNbValue, LDAPValue. However, if LDAPValidateAdd and LDAPValidateModify have been used with this same DN, the local object is automatically updated.
