Openfire 3.9.3 + AD + Miranda IM: contacts don't update

Hello everyone. We have an Openfire 3.9.3 server on MSSQL database, linked with Active Directory, and Miranda IM as a client. But there is a problem. After changing some user information in Active Directory (such as email, phone number, etc) Openfire updates it’s database pretty fast - in a matter of hour or two. But Miranda does not, it stores contacts in local dat. file, and there is two ways to update contact information: delete it and restart Miranda or right mouse click on contact and select “user information” (or something like that, I don’t have english version). Well, i hope there is a way to make Miranda update contact-list from server, because we had a massive “email-changing event” recently, and I don’t want to manually update contact-lists on 60 computers.

Thank you for your attention. Sorry for possible mistakes by the way, english is not my native language. : )
