Error message at the first phase in naming a user to another ou

Hi

I still have an error message when trying to move a user to another ou. The error message I have now is : “A required certifier entry was not found in the Name and Address Book; consult the Notes Log for details on the specific entry”

Here is a part of my code. The error occurs at the last line in code below.

ThisName = doc.FullName(0)

NewOu = doc.OU(0)

Set adminp = session.CreateAdministrationProcess(strRegServer)

Adminp.CertifierFile = strIDFile

adminp.CertifierPassword = strCertPW

noteid = adminp.MoveUserInHierarchyRequest( ThisName , NewOU, True )

In this forum I could not find any help. The Knowledge base of IBM did had a kind a similar error message( A required certifier was not found in the Name and Address Book). But the technote was assuming that I did not had a certifier created in the addressbook ( which is not the case). I even recreated the certifiers but that still did not solve the problem.

Regards
