Reassignment of password policy

[Ca...@ibs-ag.com]

Hi Folks, last question today.

I have two types of users -  'inside' and 'outside' . There exists a password policy for each type.
When users are created, the pwdPolicySubEntry attribute is added with the DN of the relevant policy. - OK

We have a case were users can be moved from inside to outside and vice versa.

LdapContext.rename(strOldDn, strNewDn);

Moving the user object as shown above works fine but I cannot figure out how to update the policy afterwards.

Tried to replace or delete the attribute, the following exception occurs.
[LDAP: error code 50 - INSUFFICIENT_ACCESS_RIGHTS: failed for MessageType : MODIFY_REQUEST Message ID : 45     Modify Request

Is there a way to do this without creating a new entry and copying all the attributes?  Thanks Carlo
