is there any way to restrict Users/Groups Login to a specified IP? I didn't find anything in the docs nor this Forum.

I only found the global zimbraWebClientLoginURLAllowedIP Attribute, but this seems not to work. (I tried setting up via zmprof mcf and admin Console, but i'm still able to log in from other IPs)

THX for your Help!
