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 object modification speed, modifications are defined locally: a single communication with the server is established when the modification is validated. The steps are:

Start modification (LDAPStartModify)
Modification operations:
- Add attributes and their values LDAPAddAttribute).
- Delete attributes (LDAPDeleteAttribute) or their values (LDAPDeleteAttributeValue).
- Replace values of an attribute (LDAPReplaceAttribute or LDAPReplaceAttributeValue)
- Rename attributes (LDAPRenameAttribute)
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).
