Steps to set up NTLM Single Sign On for eGroupWare 1.6+
|
||||
=======================================================
|
||||
(Version: $Id$)
|
||||
|
||||
NTLM SSO removes Windows users on a PC, which is a member of a Windows domain
|
||||
and who are logged into that domain, from the need to explicitly log into eGW.
|
||||
They simply point IE to the eGW URL (eg. http://domain.com/egroupware/) and
|
||||
start working. They can of cause explicitly log out and log in as an other user.
|
||||
|
||||
Firefox (at least 3.6) requires to manually enable NTLM Auth via about:config:
|
||||
search for ntlm and set "network.automatic-ntlm-auth.trusted-uris" to the domain
|
||||
your EGroupware install is using. Otherwise you will only get a popup to enter
|
||||
username (with prepended windows domain eg. DOMAIN\username) and password.
|
||||
|
||||
Here's in short what you need:
|
||||
-----------------------------
|
||||
1. eGW 1.6 running on Apache
|
||||
2. a fully working and configured winbind configuration (not described here)
|
||||
3. mod_ntlm_winbind (eg. for openSUSE from their package apache2-mod_auth_ntml_winbind)
|
||||
4. an Apache configuration with the egroupware.conf in this directory (expecting eGW
|
||||
to be installed in it's default location /usr/share/egroupware) or port the necessary
|
||||
settings to your Apache configuration.
|
||||
--> You NEED to change the domain from "TEST" to your used domain name!
|
||||
5. Make the following changes in eGW's setup >> configuraition:
|
||||
- HTTP auth types (comma-separated) to use without login-page, eg. "NTLM": NTLM
|
||||
- Select which type of authentication you are using: ADS
|
||||
This is not needed for NTLM authentication, but allows the users to use their windows
|
||||
user and password to log into eGW, if they log in using an other browser or location.
|
||||
- Host/IP Domain controler: ... <-- NEED to be filled out
|
||||
- Domain name: ... <-- NEED to be filled out, same domain name as above
|
||||
6. If you use EMail, you have to explicitly specify user/pw to use for contacting the IMAP
|
||||
(and SMTP) server, it's no longer available to eGW!
|
||||
|
||||
Please note the DC has to be started before you start winbind!
|
||||
|
||||
The eGW code should work with every Apache authentication, which sets REMOTE_USER and AUTH_TYPE.
|
||||
With slight modifications (different var names) it should work eg. with SSL client certificates.
