LDAPReplaceAttribute (Function)
Replaces all the values of an attribute by a specific value.
Ejemplo
// Modifies a specific value of an attribute 
// (the read operation was performed on the server beforehand)
// The existing values are found in sValue1, sValue2 and sValue3
// sValue2 must be replaced with sNewValue
LDAPStartModify("SessionName")
LDAPReplaceAttribute("SessionName", "AttributeName", sNewValue)
LDAPAddAttribute("SessionName", "AttributeName", sValue1)
LDAPAddAttribute("SessionName", "AttributeName", sValue3)
LDAPValidateModify("SessionName", "DN")
Sintaxis
<Result> = LDAPReplaceAttribute(<LDAP session> , <Attribute name> , <Attribute value>)
<Result>: Boolean
  • True if the modification was performed,
  • False otherwise. ErrorInfo returns more details about the error. The modification will be performed during the call to LDAPValidateModify.
<LDAP session>: Character string
Name of LDAP session used.
<Attribute name>: Character string
Name of attribute to use.
<Attribute value>: ANSI character string
New attribute value.

Differences between LDAPReplaceAttribute and LDAPReplaceAttributeValue

LDAPReplaceAttribute is used to replace all the values of an attribute by a single value. A multi-valued attribute (several values for this attribute) will become a single-valued attribute (a single value for this attribute).
LDAPReplaceAttributeValue is used to replace a specific value of an attribute by a new value. A multi-valued attribute remains a multi-valued attribute.

Modifying an existing object on an LDAP server

To modify an existing object in an LDAP server, you must define the different modifications to perform.
To optimize object modification speed, modifications are defined locally: a single communication with the server is established when the modification is validated. The steps are:
  1. Start modification (LDAPStartModify).
  2. Modification operations:
  3. Validate the modifications on the server (LDAPValidateModify). The modifications are performed on the server according to the order used in the WLanguage code.
Please note As modification operations are performed locally before being transferred to the server, it is essential to respect the logical order of modifications (for example, it will not be possible to modify an attribute deleted by the previous line of code).
