Ever since upgrading to 8.0.1 on our servers, we cannot use webaccess to add proxy rights for external entitites.

Meaning:

user1 is an external entity setup as limited license
We login as that user into the webaccess just fine. Click Options -> Proxy Access. Use the Address book, find the user we wish to give access to, click OK.

Then when we select the boxes to click add/save/whatever, it changes the format from lastname, firstname to:
firstname lastname
and then says it cannot find the user

This is 100% reproducible on ALL accounts.

BUT only if the users do NOT have their sorting/name completion by firstname/lastname.

The default is lastname, firstname.

But I'm special and have mine set to firstname, lastname, so it works for me.

How to fix this?
