I don't understand exactly what you're up to.  There's no really good
reason to install Cygwin as SYSTEM user.  You can install it just using
any administrative account, that should lead to the most servicable
results.  The "there's only one single godlike admin account called
root" concept of Unix is only partly imposable on Windows.

Re: SYSTEM as root user

[Jaspreet Singh]

The reason is something that most of the people not be interested.

Reason is that i am tring to port Webmin+Virtualmin to the Cygwin for web
Administration as it is. I ran webmin as SYSTEM user and in cron module i
 gave it command like 'su USER -c "crontab -l"'. So webmin is now write 
crontab for other users. The reason is that SYSTEM user can 'su' to any
 user without any password needed now the problem is that webmin 
knows 'root' as superuser as it is in native in any linux system and in 
the cygwin it is 'Administrator' user it runs everything as it is supose 
to be but the problem comes when it is permissions on the conf files and 
other under /usr/local/webmin. I was just gussing that if i made SYSTEM
 user as root user then the problem with the permissions will go
away the only problem is that i cant ssh or anything else similar
by root user as it will be SYSTEM user and it does not have any password
then the question apears what will happen to other application under
that are under cygwin like chmod, named, httpd, and all the others.

the procedure i thought is following in steps

run bash as SYSTEM user (i got code how to do that)

run setup.exe (i am using Cygwin 1.7)

install just for me

edit passwd to make copy of SYSTEM User to above all others and rename to
root, Administrator become admin

install webmin as root user 

what will next happen dont know

Why webmin - it can do crontab for others, useradmin works fine, even mount
works fine, and bunch of other things too

I assume you read the Cygwin user's guide about NT security.  So you
know you can tweak /etc/passwd and rename SYSTEM to root and see what
happens.

Public key authentication allows to logon as SYSTEM using ssh.

Btw., nothing keeps you from patching webmin to recognize the SYSTEM
user as root user as well.

Re: SYSTEM as root user

[Jaspreet Singh]

yes, you are right i thought of that too but i just gussing that reward to
be root user goes to SYSTEM rather than Administrator coz SYSTEM has
 capability to use 'su'. Just a guess but you are right its easy to patch 
webmin to recognize SYSTEM not root than going into all the way installing
Cygwin as SYSTEM and the making is root User. 

Thanks

Re: SYSTEM as root user

[Jaspreet Singh]

ok, Webmin got patched thats done, Now problem is that i just
creted a new user 'test' with the help of useradmin module that worked
fine too, user is added by my perl script that adds user to windows
account then with /mkpasswd adds it to /etc/passwd, means thats valid
but runing /bin/bash as SYSTEM get me to su root that is
Administrator and even su to my User that is jaspreet member of
Administrators group but it does not get me to su user 'test' that 
i just created. I think SYSTEM can su to any User. What about cyglsa
or that CYGWIN=server passwd -R, can any of this can help.

Any idea
