net ads join when using a precreated computer object and using credentials from a different domain does not add the SPN or DNS attributes

[Richard Sharpe]

Hi folks,

With Samba 3.6.x net ads join we are seeing cases where if you join
with a pre-created computer object and use credentials from a
different domain in the AD forest, the SPN and DNS attributes are not
added to the computer object.

Is this a known bug?
