Re: [otrs] Re: LDAP Authentication using Microsoft Active Directoryserver

24 Sep 2007

      Mike,

For Unix, as per http://doc.otrs.org/2.2/en/html/x354.html, you would  
need Net::LDAP. To install the module via CPAN, you'd type in:

perl -MCPAN -e 'install Net::LDAP'

or, alternatively some Unices allow:

cpan Net::LDAP

To answer your second question, you'd login via "username" or  
specifically the sAMAccountName LDAP attribute in Active Directory.

Robert and or anyone that can assist.  2 quick questions…
Do you have any instructions on how to install the correct PERL  
Ldap modules?
When you login to OTRS do you use the username or domain\username?
Thanks for any help offered. I have been chasing this issue for  
well over a month.

Edward,
Thanks for the suggestion.  I copied your configuration and now  
have both agents and customers successfully logging in with  
authentication against our AD server.
Thanks!!!

Robert,
I would suggest trying to simplify the configurations by removing the
AlwaysFilter and specifying the root of your Active Directory as the
BaseDN. Once it authenticates properly you can start customizing and
narrowing the BaseDN scope.
Here is an excerpt from Config.pm which I just tested on our dev
environment as we don't use the customer interface in production. It
properly authenticated and pulled in all the proper values into  
OTRS...

Thanks for the suggestion, Edward.  Changing the SearchUserDN to
<username>@<domain> continues to work for the agent login.  I still
haven't been able to get the customer login working.  Any hints?

Robert,
You may also try <username>@<domain> which is the new Microsoft

for specifying users within domains. This is what we use in
configuration...

I changed every entry of:

to:
'tsteel\OTRS'
and, to pull user data to the local DB, I added:
# UserSyncLDAPMap
    # (map if agent should create/synced from LDAP to DB after

    $Self->{UserSyncLDAPMap} = {
        # DB -> LDAP

Perhaps this will help someone else who's trying to set OTRS up
with Microsoft Active Directory.

folks,
First let me say that OTRS appears to be a great product!   
Kudos to
the developers!
We are in the process of evaluating our options for a helpdesk/
trouble-ticket system.  I would really like to give OTRS a good
evaluation, but I'm having some problems.  Our chosen solution  
must
be able to authenticate users (both agents and customers) via
Microsoft Active Directory.  It appears that this is possible, but
I've yet to have any success.  I'll outline the steps I've taken
and solicit any input from the community.
OTRS is working fine when authenticating against it's own
database.  Here's what I've done to try to authenticate against  
AD:
I edited Kernel/Config.pm and added:

    },

    CustomerUserListFields => 'sAMAccountName', 'cn', 'mail',
    CustomerUserSearchFields => 'sAMAccountName', 'cn', 'mail',
    CustomerUserPostMasterSearchFields => 'mail',
    CustomerUserNameFields => 'givenname', 'sn',
    Map => [
    [ 'UserFirstName', 'Firstname', 'givenname', 1, 1, 'var' ],
    [ 'UserLastName', 'Lastname', 'sn', 1, 1, 'var' ],

<end additions to Config.pm>
On my AD box, I ran: ldifde -f users.ldf -d "OU=Tuscaloosa - Sheet
Mill,dc=tsteel,dc=com" -r ""
Which returned a listing of all users in the Tuscaloosa - Sheet
Mill org unit.  Within the users.ldf file (output from the above
command), there's an entry for OTRS Admin:

my username (which I know is valid in AD), it errors out with:
Login failed! Your username or password was entered incorrectly.
And, when I revert the Config.pm back (so I can log in) and check
the system log, I see:
User: raldridge authentication failed, no LDAP entry found!
BaseDN='ou=Tuscaloosa - Sheet Mill,dc=tsteel,dc=com',
Filter='(sAMAccountName=raldridge)', (REMOTE_ADDR: 10.1.1.50).
Any help would be greatly appreciated.
