Im having this rather odd issue with spark. Using version 2.5.7 for Windows.
I have Openfire 3.4.0 on a Windows 2003 Sp2 machine, using Ldap auth and groups.
Here is my issue, if I set spark to: Group offline users, giving the group called: “offline group” if I disable that feature, I have user names repeated in the groups represented. See attachment.
I can repoduce this at will, on multiple user’s clients, so its not just mine.
