Contact List update status

I am using Openfire 3.6.0 with Spark 2.5.8.

The contact list does not properly update the status of users who are logged without logging out of the client and logging back in.

The contact list comes from a Windows 2003 Active Directory. The shared/contact groups in openfire are security groups in Active Directory. Is there a setting in openfire or spark to increase the contact list refresh time?
