Good morning, we are seeing a new issue with our login script for the user's home directory

Currently we are using

Map Root H:=\\axxxx\addddd\home\%login_name

We are seeing users that have user names longer than 8 characters.

We are trying

Map root H:=\\axxxx\adddd\home\%CN

Has anyone else seen issues with over 8 characters in the login user names?
