ModifyDNRequest
This request is used to move entries or to rename entries or to move and rename entries. Its counterpart in a ldif file is a 'changetype: moddn' or a 'changetype: modrdn' operation (moddn or modrdn are synonymous).
We will separate the ModifyDN into 3 different cases :
- A simple move operation : we change the superior, the RDN remains the same
- A rename operation : the RDN is changed
- A move and rename operation : a combinaison of both previous operations
Move Move operation
This is the simplest one : we change the superior, without changing the entry's attributes nor the RDN
the the following entry :
| No Format |
|---|
cn=test, dc=example, dc=orgobjectClass: personobjectClass: topcn: test
|
...
We also have sub cases, depending in the presence (or not) of the new RDN AVAs into the initial entry. Rge following table expose all the different cases (28), assuming that the two subcases are :
- The The initial entry does not contain any of the RDN AVA
- The The initial entry contains at least one of the RDN AVA which is not part of the original RDN
