[horde] horde discloses login names

[A. Schulze]

Hello,

while setting up public accessible services I noticed that horde show
real owner names and sometimes show login names. This is not consistent.
I would like to avoid login names disclosed at all.

My public accessible gallery show some screen shots it illustrate the issue:

Are there settings to avoid login names to be shown at all?

Thanks
