User cannot login using AD credentials, others can
Still not exactly sure what caused this, but here is what I did and it worked.  

On the old iMac:


Unbound from domain and logged user out


In active directory:


reset the users password


Now I am able to login to the MBP with the AD network account to create the mobile account.  Hopefully this helps someone else if they come across this.  At first glance this just sounds like incorrect password, but using the right password would not add to the badpwdcount in AD, and using an incorrect one on purpose would.  Also the original iMac &amp; a Windows machine were able to login to the mobile account using the correct password.
