I can never contact my domain controller, which is on
the same machine as the cygwin.
The prompt suggests that you are logged in as 'administrator', not as
'mblanco' so you will need to set up the account 'administrator' properly
in cygwin if you want things to work in that context.
As Holger asked, are you sure that "bgchemical.com" is your windows domain
name? Are you perhaps confusing Internet domains (as in DNS, FQDN and names
like 'example.com') with Windows Domains (as in PDCs, BDCs and these days
Active Directory). The terminology is somewhat confusing, especially since
the two kinds of domain can be linked if the Windows Domain Administrator
knows what they are doing (see Gary's response to your question). Even if
the Windows Domain and DNS have been set up so that they work properly
together, my quick experiment suggests that you do not use a FQDN for the
'-d' parameter to mkpasswd.
On the subject of domain controllers, if you can log in as administrator on
a machine that is running a Windows Domain Controller then I would hope
that you know far more about being Windows Domain Administrator than I
remember from the Windows NT Admin course I did nearly 10 years ago. If you
meant that you are running a DNS server then that is an entirely different
Two things to do to get some basic information before going any further:
At a Windows Command Prompt type
This should respond with
For values of DOMAIN and user that match what you use to log in to Windows.
Then from a cygwin shell type
echo -u "$USERNAME" -d "$USERDOMAIN"
the USERNAME and USERDOMAIN environment variables should be set to the
values reported by whoami (Note that there is also a whoami command
provided by cygwin - it is not the same thing as the Windows command).
If the values matched, in a cygwin shell type
mkpasswd -u "$USERNAME" -d "$USERDOMAIN"
This should respond with the line you need to put in your /etc/passwd to
make things work for the user you are logged in as.
One final point. In the extract quoted above you used '> /etc/passwd' for
the second call of mkpasswd but this will replace the previous contents of
/etc/passwd deleting all the local account data. You should use '>>
/etc/passwd' to append the extra line.
