It seems from the old discussion that the patch was complex - as far as I can digest, it even added NG management options into UI.
That’s great, but for us (who don’t manage AD from EGw) it would be vastly sufficient if only EGw was able to correctly read user’s membership thru NGs, in order to get ACLs etc to proper shape. I hope this is simpler goal to reach, probably in scope of some functions change.
It is not critical for us either. We are implementing a workaround - script-generated technical groups specially for EGw, filled by original AD groups members. But I admit such a solution dosen’t look “nice” nor modern.
