Manual user add + auto users = some users w old names

I dont know if this would be a spark or openfire support question, anyway, here it goes…

Our userbase is within a LDAP server. Openfire is well configured and it properly populares spark users w other users and their groups.

Thing is, before we add group share and auto accept invites, some users added others by hand and defined their names themselves.

Recent clients dont have to add or authorize other users and for them all usernames are populated properly, but those old users who added other users themselves will see custom usernames as they defined when adding users by hand.

How do I remove custom names from users roster list and leave them only w the server provided list? Its probably an Openfire thing since the custom names shows up even on new installs for these old users.

thanks,

Caio.
