Unknown+user issues using cygwin under an Azure AD "domain" account on Windows 10.1511?

Unknown+user issues using cygwin under an Azure AD "domain" account on Windows 10.1511?

[Russell Mora]

Hi All,

Big fan - long time user, first time mailer! :-)

Quick check - I'm seeing Unknown+user issues even since I started
logging in via an Azure AD "domain" account - I put "domain" in quotes
because Azure AD is not full AD domain services, just the identity
services (likely cause of my failure....)

Anyway, this is what I see:

==============
C:\WINDOWS\system32>whoami
azuread\russellmora

C:\WINDOWS\system32>
==============

I used the 2.873 64-bit installer and did a basic install. When I
first fire up cygwin (from c:\cygwin64\cygwin.bat) I see this (note
the home dir and whoami are different, plus what to me seems like
unusual permissions for my home dir):

==============
Copying skeleton files.
These files are for the users to personalise their cygwin experience.

They will never be overwritten nor automatically updated.

'./.bashrc' -> '/home/RussellMora//.bashrc'
/usr/bin/install: cannot create regular file
'/home/RussellMora//.bashrc': Permission denied
'./.bash_profile' -> '/home/RussellMora//.bash_profile'
/usr/bin/install: cannot create regular file
'/home/RussellMora//.bash_profile': Permission denied
'./.inputrc' -> '/home/RussellMora//.inputrc'
/usr/bin/install: cannot create regular file
'/home/RussellMora//.inputrc': Permission denied
'./.profile' -> '/home/RussellMora//.profile'
/usr/bin/install: cannot create regular file
'/home/RussellMora//.profile': Permission denied

$ whoami

$ ls -la

$ uname -a
CYGWIN_NT-10.0 Lenovo-PC 2.4.1(0.293/5/3) 2016-01-24 11:26 x86_64 Cygwin

==============

This all started because I was getting the "Failed to fork child
process: No such file or directory." issue when starting cygwin from
the start menu.  I did a clean install with clean registry but that
didn't help.

Any ideas?

Cheers,
Russell

Finally occurred to me to run whoami under strace - I saw this which
was of interest:

========
 2706   10005 [main] whoami 13636 pwdgrp::fetch_account_from_windows:

========

Went back to the Windows version of whoami and got this:

========
C:\WINDOWS\system32>whoami /fqdn
ERROR: Unable to get Fully Qualified Distinguished Name (FQDN) as the current
       logged-on user is not a domain user.

C:\WINDOWS\system32>
========

Yeah... I'm not too surprised it doesn't work....

Cheers,
Russell.
