# It appears that with ADmitMac v7 on OS X 10.7 and 10.8, the local Directory Services accounts 
# for Mobile Accounts are created without any reference to the sAMAccountName.
# 
# This means that user record names do not shown in the alias field of the users accounts in System Preferences
# 
# For example jbloggs logs in the first time ok but subsequent logins will only work with jbloggs@FQDN
#
# Alternatively i have created this script to run as a login policy to address this issue.
