qpopper authentication problem

qpopper authentication problem

[Vince Hoffman]

	I seem to have developed a problem with qpopper and thought i'd
bother the list before i tried Pierre Humblet,
it could be a qpopper specific question in which case feel free to tell me
where to go, er point me in the right direction ;)

I have it running from inetd with inetd as a service (running as SYSTEM),
(this works for ftpd and telnetd so i'm happy with my inetd setup.) the
inetd.conf entry is
pop3   stream   tcp   nowait   root   /usr/local/sbin/popper popper -p 2
(-p 2 allows plain text passwords)

permissions on /var/mail are as follows

drwxrwxr-x    2 SYSTEM   mail            0 Sep  3 22:48 mail

$ uname -a
CYGWIN_NT-5.0 JHARY 1.3.12(0.54/3/2) 2002-07-06 02:16 i686 unknown

(mail group exits for exim which is working fine :) 

the error i get from my pop client is
"There was a problem logging onto your mail server. Your Password was
rejected. Account: 'jhary.unsane.co.uk', Server: 'jhary.unsane.co.uk',
Protocol: POP3, Server Response: '-ERR [SYS/PERM] Temporary drop
/var/mail/.vince.pop not owned by vince.', Port: 110, Secure(SSL): No,
Server Error: 0x800CCC90, Error Number: 0x800CCC92"


client is outlook express 5, yes i know i should get a real one but it used
to work.

this was working until recently when i must have changed something, sadly i
have no idea what. all i can think i did was the usual upgrades of installed
cygwin software.
any ideas ?

as an aside since i see exim is now available from the installer (must have
missed the anouncement.) i came across a replacement for the bsd mail
program here http://omnibus.uni-freiburg.de/~gritter/ that will compile
nicely with only minor adjustments due to windows dislike of 'special'
filenames (rename aux.c to aux1.c and a s/aux.c/aux1.c across the source
although this must be done on a linux/unix box due to the aforementioned
filename issue ) if you make a symlink from exim to sendmail (messy but we
arent getting sendmail soon are we ?)


and i'd just like to add, many thanks to all the cygwin developers for
helping make windows more bearable.

RE: qpopper authentication problem

[Vince Hoffman]

oops meant to reply all before. 
I tried deleting and it just recreated it with the same permissions and
giving the same error.
However i noticed various errors in my exim logs, regarding uids and being
unable to setuid, and mail had stopped being delivered while i had it
running as exim user (even though i had given it the permissions specified
in the README,) i switched to running as SYSTEM and changed a few
permissions and basic mail started being delivered (rather than frozen)
again. so i'm going to try and Full reinstall of cygwin, as i must have made
a serious change without realising it. If that doesnt fix it i'll let you
know.

Re: qpopper authentication problem

Thanks a lot, this was exactly what I missed ;o)
I was launching popper.exe from user account instead of system account.
Works great now ;o)

Thanx again

qpopper authentication problem

My password is rejected whatever I do.
I tried with several users that are well defined in /etc/passwd and the =
result is always the same.
I tried with ntsec enabled and disabled, no way.

Please could someone help me to solve this problem ? Maybe there is =
something I don't understand...

I think it is a general cygwin related authentication problem (a really =
common problem ;o)
Concerning Authentication mechanism in cygwin, may i ask if it would be =
possible that someone write a document about this issue ???
I'd do it myself if i had the skill which is not the case unfortunatly. =
And this problem is so recurrent that I think it would be worth the work =
..

Thanks a lot

Thomas

Besides http://cygwin.com/cygwin-ug-net/ntsec.html there's not much
to talk about.  Cygwin authentication depends on the same rules as
Windows authentication.  A process which want to change user context
with password authentication needs "Act as part of the operating system",
"Replace process level token" user rights, a process which wants to
change user context just by using setuid() (using NT's NTCreateToken())
needs the "Create token object" and "Replace process level token" user
rights.  This means basically that under default conditions only
SYSTEM has the permissions to change user context.  Normally you
should start such a process as service.
