passwd -R

passwd -R

[Vijay K Sukthankar]

Hi,

I am trying to decipher how to do some of commands on a cygwin shell
remotely. I am using a Jython script to reset the Admin password and I
understand that I would have to do the following

1) change the password registry entry using passwd -R
2) net user Administrator <new password>

When the command is executed it expects that a re-enter of password which I
dont want. Is there a way I can do echo passwd | passwd -R which would
change the password in registry.

Regards

Hang on.  You only need to do this if you use the account for login
purposes where you don't want to give your password, according to
http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-setuid-overview

> 2) net user Administrator <new password>

Otherwise this command or just using the Cygwin passwd command without
the -R option is sufficient:

That's not provided for.  You could try to give the password twice

  echo -e "${pwd}\n${pwd" | passwd

but no guarantee that it works.  Alternativly you write a tiny tool
which calls the Win32 function NetUserChangePassword:

Looks ok.  It's a change in utils.  No worries.

OK.  I'll have to pull from the mirrors and then roll a new snapshot package
locally.  BTW, the ChangeLog for that snapshot looks like it might have a
typo in the last date, or is this really from February?

That's very likely the problem introduced by changing the default mutex
type and fixed in 1.7.31-2.  The getpass function hangs due to the main
thread's mutex not being a PTHREAD_MUTEX_RECURSIVE.

2014-07-24 is such a snapshot, basically what I just upload as 1.7.31-3,
plus all the AD integration stuff.

passwd -R

[Achim Gratz]

I've been running with the latest LDAP enabled snapshot from 2014-07-14. 
With this snapshot the "passwd -R" hangs when trying to set or delete the
password on the server.  The snapshot from 2014-07-09 works correctly in
that respect.

Would it be possible to roll a new LDAP enabled snapshot with all the fixes
based on the latest Cygwin release, please?


Regards,
Achim.
