Remarks

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:

Initializing the modification (LDAPStartModify)
Modification operations:
- Adding the attributes and their values (LDAPAddAttribute).
- Deleting the attributes (LDAPDeleteAttribute) or their values (LDAPDeleteAttributeValue).
- Replacing the values of an attribute (LDAPReplaceAttribute or LDAPReplaceAttributeValue)
- Renaming the attribute (LDAPRenameAttribute)
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).
