domain\user form now works. user@domain format already worked but now
fixd to allow local machine name as the domain name also. So all these
formats now work:
For a domain acct: user OR domain\user OR user@domain
For a local acct: user OR localmachinename\user OR
user@localmachinename
Note: public key logon still only works for a local user acct and the
localmachinename must not be given and only the username specified for
public key logon to work.
