RE: Non-privileged use can't logon

["Max Rockliff" <max dot rockliff at bigpond dot com>]

Hey Corinna,

You're a magician.  It seems to have fixed the problem, or at least provided an effective workaround.  Here's a transcript (kinda)

1.  Downloaded the new cygwin1-20150311.dll.xz  (PS. Kudos for using a yyyymmdd format in the name - I always do, but so many don't
2.  Copied the xz file to my privileged user account home folder and Unxz'ed it.
3.  Used Windows to copy the file cygwin1-20150311.dll to the C:\cygwin\bin folder
4.  Stopped the SSHD service
5.  Renamed the old cygwin1.dll to cygwin1.dll.old
6.  Renamed cygwin1-20150311.dll to cygwin1.dll
7.  Started the SSHD service
8.  Started the terminal
9.  Executed ssh st@localhost and it logged on successfully no errors.
	Max@Max-PC /bin
	$ ssh st@localhost
	st@localhost's password:
	Last login: Wed Mar 11 20:32:00 2015 from ::1

	st@Max-PC ~
	$
10.  And, as we like to say in Australia - Sweet!

What on earth did you change that made the error go away?

Max

Thanks for the info.

Depends.  As for the actual cause why userenv.dll refuses to load, no.
It's just a simple LoadLibrary call, nothing fancy.  I just tried the same scenario on my local 8.1 test machine and logging in with an unprivileged account worked fine.

I tried to come up with a workaround for the problem, though.  I just uploaded a new developer snapshot to https://cygwin.com/snapshots/

Just fetch the latest 32 bit cygwin1.dll, http://cygwin.com/snapshots/x86/cygwin1-20150311.dll.xz

Unxz it, chmod +x it.  Stop all Cygwin processes.  In Windows Explorer, open the C:\cygwin\bin directory.  Rename the original cygwin1.dll to cygwin1.dll.ORIG.  Move the new cygwin1-20150311.dll into place and rename it to cygwin1.dll.  Retry your scenario.  And please report back.


Thanks,
Corinna
