LDAPReplaceAttribute (Function)
In French: LDAPRemplaceAttribut
Replaces all the values of an attribute by a specific value.
Example
// 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 by sNewValue
LDAPStartModify("SessionName")
LDAPReplaceAttribute("SessionName", "AttributeName", sNewValue)
LDAPAddAttribute("SessionName", "AttributeName", sValue1)
LDAPAddAttribute("SessionName", "AttributeName", sValue3)
LDAPValidateModify("SessionName", "DN")
Syntax
<Result> = LDAPReplaceAttribute(<Session Name> , <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.
<Session Name>: Character string (with quotes)
Name of LDAP session used.
<Attribute Name>: Character string (with quotes)
Name of attribute to use.
<Attribute Value>: Ansi character string (with quotes)
New value for the attribute.
Remarks

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 the modification speed of objects, the modifications are defined locally: a single communication is established with the server when validating the modification. The steps are as follows:
  1. Initialize the 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.
Caution: These operations being performed locally then on the server, the logical order of the modifications must be respected (you cannot for example modify an attribute that was already deleted by the previous code line).
