This system has been functioning fine for over a year then yesterday our contact list vanished from spark. I can see all the contacts in the admin console and we can login to spark no problem.
Ive upgraded the server from 3.10 to 4.1.1
purged the server install and started new
deleted spark 2.7.7 from my workstation and all associated folders in AppData
upgraded to 2.8.1
Nothing has helped so far.
We are using Openfire 4.1.1 (Ubuntu '16.04.1 LTS' ) and Spark 2.7.7 (Windows 7). LDAP / Active Directory user propagation.
