Under the HKLM\SOFTWARE\OpenAFS\Client\Realms key create a key for the
realm name you are using and then create subkeys for each cell you wish
to have tokens acquired for.

If the Realm is AD.FOOBAR.COM and the cell is foobar.com create a key
for

  HKLM\SOFTWARE\OpenAFS\Client\Realms\AD.FOOBAR.COM\foobar.com

within that key you can create REG_SZ values for the configuration
parameters

	MethodName 	REG_SZ  Kerberos5
  	Realm		REG_SZ	AD.FOOBAR.COM
	
When a Kerberos v5 identity is created in the AD.FOOBAR.COM realm
the foobar.com AFS cell will be added to the configuration.
