Problem
AD integration is not working "locked out"
Resolution
Weblabselfhost.config find "usead" set it to 0
restart the exterroweblabselfhost service
login as local admin (user should know this)
Fix AD>test >close the app
Back to Weblabselfhost.config find "usead" set it to 3
restart the exterroweblabselfhost service
and log in as AD user
Cause
AD or LDAP server is off line, moved, changed name/address, or otherwise broke
