Why does mkpasswd -c use a different offset? Corinna?

Why does mkpasswd -c use a different offset? Corinna?

[Houder]

Hi Corinna,

I am confused ... the output from mkpasswd -c is NOT the same as the output from mkpasswd -l -u <current user> on
both my "Cygwin-32" and my "Cygwin-64".

As an example, the output on my "Cygwin-64":

64-@@ uname -a
CYGWIN_NT-6.1 Seven 1.7.32(0.274/5/3) 2014-08-13 23:06 x86_64 Cygwin
64-@@ id
uid=1000(Henri) gid=513(None) groups=513(None),545(Users),1007(HelpLibraryUpdaters)

64-@@ grep Henri /etc/passwd
Henri:unused:1000:513:U-Seven\Henri,S-1-5-21-91509220-1575020443-2714799223-1000:/home/Henri:/bin/bash
64-@@ mkpasswd -l -u Henri
Henri:unused:1000:513:U-Seven\Henri,S-1-5-21-91509220-1575020443-2714799223-1000:/home/Henri:/bin/bash

64-@@ mkpasswd -c
Henri:unused:11000:10513:U-Seven\Henri,S-1-5-21-91509220-1575020443-2714799223-1000:/home/Henri:/bin/bash
64-@@ mkpasswd -C

Note the difference between the output from 'mkpasswd -l -u Henri' and 'mkpasswd -c' (i.c. uid and gid). It is
not what I expect (i.e. I do not understand).

Please, enlighten me ...

Thanks, Henri

Are you logged into a domain?

-c would give you the domain user in that case
-l would give you the local user

Hi Mr.? "Simple",

No, I am not. That is, Seven (my machine at home) does it all by itself ("stand-alone").

... meaning? mkpasswd -c (and mkgroup -c) should not yield any output in my case?

I reread the description of both commands in the User Guide ... it did not help to remove my confusion.

It's a bug.  Funny that this has never been reported before.

It shouldn't matter anymore, though, because mkpasswd is changing
significantly with 1.7.33.  I would suggest to take a look into the
current test release 1.7.33-0.3.  The mkpasswd command will produce
the same uid and gid values as the values generated by the Cygwin
DLL in "db" mode to avoid collisions.

... aha, that makes sense.

Aha ... I have already replaced the cygwin1.dll (on my Cygwin-32) with
the one from the snapshot ... apparently, that is not sufficient ...

Thank you very much for your clarification!
