[Samba] Samba authentication against an NT group in Apache

[PIGNOL, Christian]

Hi,

I have exactly the same problem with my web server ...

Linux/redhat	9.0		/ kernel 2.4.20-20.9.1 (+ Acl patches)
Samba			3.0.2a	/ compiles with winbind and Acl options
Apache		2.0.40	/ with mod_auth_pam 2.xx included

Authentication to samba share from a windows workstation using Acl + winbind
+ "Nt domain groups" works fine.

But I gave some problems when I want to use NT domain groups to restrict web
access to web directory ... only single user autorization works fine but ...
never with a domain group ...

Note that single authorization works fine but in sensitive case mode ...
If I specify "require group MyDomain\MyUser" in the ".htaccess" file, I MUST
exactly type "MyDomain\MyUser" on the keyboard when the identification box
appears ! It doesn't work if type "mydomain\myuser" !

Do you have solved your problem or found an acceptable solution to use
domain groups ?

Thanks a lot for your help.

Subject: [Samba] Samba authentication against an NT group in Apache


We would like to have our Apache Linux-based web server use our
existing NT domain to authenticate some of our web pages. We are using
the Apache module mod_auth_pam to use pam-based authentication and
then the winbind pam module to do the actual authentication.

We have gotten to the point where we can authenticate using NT
_users_, but we have not been able to authenticate using _groups_. For
example, we can restrict a web page so that only the NT user
"joeuser" can gain access to the page, but we have been unable to
configure Apache so that any user of the NT group "SpecialAccess" (of
which joeuser is a member) can gain access but no one else. 

Here is the .htaccess file we used to try to do this: 
##########################
AuthPAM_Enabled On
AuthPAM_FallThrough Off
AuthAuthoritative Off
AuthType Basic
AuthName "test"
require group "OURNTDOMAIN\SpecialAccess"
##########################

Apache generates the following error: 
##########################
[Mon Feb 02 16:20:40 2004] [crit] [client 130.126.35.93] configuration
error: couldn't check access.  No groups file?: /grouptest/index.html
##########################


Here are some more details on our setup: 
---------------------------------------
Linux Redhat Enterprise Linux 3
Samba Version 3.0.0-14.3E
Apache 2.0.46
mod_pam_auth 2.0-1.1.1


The configuration file that mod_auth_pam uses is called /etc/pam.d/httpd
and contains the lines
##########################
auth       required     /lib/security/pam_winbind.so
account    required     /lib/security/pam_winbind.so
##########################

The samba configuration file contains these lines:
##########################
[global]
workgroup = OURNTDOMAIN
encrypt passwords = yes
security = domain
password server = pdccontroller1
winbind use default domain = yes
idmap uid = 10000-20000
idmap gid = 10000-20000
winbind enum users = yes
winbind enum groups = yes
winbind use default domain = yes

Any ideas or suggestions are very welcome. 

Thank you. Alan L.
