How do I prohibit a change to the mailbox displayname during a user clone process? (NETIQKB23887)

goal
How do I prohibit a change to the mailbox displayname during a user clone process?

fact
Directory and Resource Administrator 6.x

fix

One solution is to use a pretask trigger to populate the property [In.MailboxProperties.cn]

The trigger would take the values of each of the properties below to generate the Displayname for the mailbox.  Therefore, regardless of what the Assistant Admin inputs for the displayname, when the clone process is submitted the trigger populates the displayname.

* [In.MailboxProperties.givenName]
* [In.MailboxProperties.initials]
* [In.MailboxProperties.sn]

A second option is to contact Professional Services.  They can customize the MMC console to grey this property out from Assistant Admins.

note
If the Exchange 5.5 autonaming policy is in effect it populates the displayname correctly during the userclone, however, Assistant Admins can still go in and change the displayname to something that does not follow the naming policy.
