How can I create a mobile account in Mountain Lion?

Dear All,

I have a problem creating a mobile account while joining an Active Directory domain controller (DC).

** Case one: While joining the DC, if these options are selected (Create mobile account at login) & (Force local home directory on startup disk), the home directory can not be created at all.

So, how can case one be solved?

** Case two: While joining the DC, if (Creat mobile account at login) is not selected, and (Force local home directory on startup disk) is selected, home directory can be creatded, but not as mobile account.

So, After creating the home directory, I can go to make it mobile account from Users & Groups/Active Directory user and choose mobile account.

after creating mobile account, the user loged out and then loged in back again. from here Mobile account botton is disabled and I can not manage it.

So, How can the bold underline part of case two be solved?

Note: Active directory used is Windows Server 2008.

Regards,

Abdelaal,
