Authenticating MRBS against Active Directory using LDAP

[Wizzer]

I've been trying to get this to work. It's fine with "config" authentication, but I want to use AD.

I've managed to get Moodle to use AD but it asks for lots more information about the LDAP server than MRBS seems to want.

Anyone got any pointers / common problems to check out?

Cheers.

(edited to remove stupidity, yes I did mean MRBS)

You do mean MRBS don't you?

Have you looked at this? You'll have to give it details of your AD setup. If you're going to use the auth_ldap method you'll also have to build/enable this in php.

More specifically:

LDAP Authentication
-------------------

There are currently three methods for doing LDAP authentication, auth_ldap,
auth_ldap.pl, auth_ldapsearch.pl.  The preferred method, auth_ldap, uses
the LDAP functionality built into PHP and is described here.  The other
methods use the 'ext' authentication method and described further on in
this file.

This method can be used by setting config.inc.php as follows:

$auth["type"] = "ldap";

Also you will need to change the section:

# 'auth_ldap' configuration settings
# Where is the LDAP server
$ldap_host = "localhost";
# LDAP base distinguish name
# See AUTHENTICATION for details of how check against multiple base dn's
$ldap_base_dn = "ou=organizationalunit,dc=my-domain,dc=com";
# Attribute within the base dn that contains the username
$ldap_user_attrib = "uid";

This method will attempt an authenticated bind to the ldap server using
the supplied password and a distinguished name, which is formed from the
base distinguished name, the user attribute and the user name. 

This method supports multiple $ldap_base_dn entries and $ldap_user_attrib
values.  The authentication is attempted with each base dn in turn until it
succeeds or it fails to authenticate the user.

Multiple base distinguished names with the same user attribute for each
base dn:
# 'auth_ldap' configuration settings
# Where is the LDAP server
$ldap_host = "localhost";
# LDAP base distinguish names
$ldap_base_dn[] = "ou=People, o=myCompany, c=US";
$ldap_base_dn[] = "ou=Administrators, o=myCompany, c=US";
#
$ldap_user_attrib = "uid";

Multiple base distinguished names with the option of different user attributes
for each base dn:
# 'auth_ldap' configuration settings
# Where is the LDAP server
$ldap_host = "localhost";
# LDAP base distinguish names
$ldap_base_dn[] = "ou=People, o=myCompany, c=US";
$ldap_base_dn[] = "ou=Administrators, o=myCompany, c=US";
#
$ldap_user_attrib[] = "uid";
$ldap_user_attrib[] = "cn";

Note: if you use the latter configuration then an equal number of base dn's
and user attributes must be specified or authentication will fail.

Yes, I've read the relavent docs. and the machine MRBS is on also hosts Moodle which authenticates against AD just fine.

This is how my config currently looks:

$auth["session"] = "php"; # How to get and keep the user ID. One of
			  # "http" "php" "cookie" "ip" "host" "nt" "omni".
$auth["type"] = "ldap"; # How to validate the user/password. One of "none"
                          # "config" "db" "db_ext" "pop3" "imap" "ldap" "nis"
                          # "nw" "ext".

# The list of administrators (can modify other peoples settings)
#$auth["admin"][] = "127.0.0.1";	# localhost IP address. Useful with IP sessions.
$auth["admin"][] = "rww";	# A user name from the user list. Useful 
                                    #with most other session schemes.

# 'auth_ldap' configuration settings
# Where is the LDAP server
$ldap_host = "server";
# LDAP base distinguish name
# See AUTHENTICATION for details of how check against multiple base dn's
$ldap_base_dn = "ou=Staff, ou=RWS,dc=royal,dc=wolverhampton,dc=sch,dc=uk";
# Attribute within the base dn that contains the username
$ldap_user_attrib = "sAMAccountName";

# 'auth_ldap' extra configuration for ldap configuration of who can use
# the system
# If it's set, the $ldap_filter will be combined with the value of
# $ldap_user_attrib like this:
#   (&($ldap_user_attrib=username)($ldap_filter))
# After binding to check the password, this check is used to see that
# they are a valid user of mrbs.
#$ldap_user_filter = "mrbsuser=y";
