LDAP authentication Errors

5 Feb 2008

      I've gone through countless LDAP documents for OTRS and I cannot for the life of me get customers to authenticate via LDAP

I am running win32 OTRS v2.1.7.

In the OTRS documentation and in the trinityhome.org documentation it says to edit the config.pm file in otrs/kernel/config.pm

I followed the instructions to the best of my knowledge.... but it was still causing customers to be authenticated via the MySQL backend.  I tried editing the config and the config.PM file in the otrs/kernel folder and still no progress.

Through SysAdmin in OTRS I have tried modifying Framework -> Frontend::Customer::Auth and then It tries to authenticate to my LDAP server and I get the following error in the Otrs.log file

Kernel::System::CustomerUser::LDAP::new][71] First bind failed! 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 525, vece

THis is trying to connect to a Windows 2k3 AD server.

Any ideas what i'm doing wrong?  Below is the code I tried using in the config.PM file that wasn't doing anything... I pasted it right above "EnD of your config options!!!"

#Enable LDAP authentication for Customers / Users
  $Self->{'Customer::AuthModule'} = 'Kernel::System::CustomerAuth::LDAP';
  $Self->{'Customer::AuthModule::LDAP::Host'} = 'DC1.United.net';
  $Self->{'Customer::AuthModule::LDAP::BaseDN'} = 'ou=Users,dc=United,dc=net';
  $Self->{'Customer::AuthModule::LDAP::UID'} = 'sAMAccountName';

#The following is valid but would only be necessary if the
#anonymous user do NOT have permission to read from the LDAP tree
  $Self->{'Customer::AuthModule::LDAP::SearchUserDN'} = 'otrs_ldap';
  $Self->{'Customer::AuthModule::LDAP::SearchUserPw'} = 'Password';

#CustomerUser
#(customer user database backend and settings)
    $Self->{CustomerUser} = {
      Module => 'Kernel::System::CustomerUser::LDAP',
      Params => {
      Host => 'dc1.united.net',
      BaseDN => 'OU=users,DC=united,DC=net',
      SSCOPE => 'sub',
      UserDN =>'otrs_ldap',
      UserPw => 'Password',
    },
# customer unique id
    CustomerKey => 'sAMAccountName',
    # customer #
    CustomerID => 'mail',
    CustomerUserListFields => ['sAMAccountName', 'cn', 'mail'],
    CustomerUserSearchFields => ['sAMAccountName', 'cn', 'mail'],
    CustomerUserSearchPrefix => '',
    CustomerUserSearchSuffix => '*',
    CustomerUserSearchListLimit => 250,
    CustomerUserPostMasterSearchFields => ['mail'],
    CustomerUserNameFields => ['givenname', 'sn'],
    Map => [
      # note: Login, Email and CustomerID needed!
      # var, frontend, storage, shown, required, storage-type
      #[ 'UserSalutation', 'Title', 'title', 1, 0, 'var' ],
      [ 'UserFirstname', 'Firstname', 'givenname', 1, 1, 'var' ],
      [ 'UserLastname', 'Lastname', 'sn', 1, 1, 'var' ],
      [ 'UserLogin', 'Login', 'sAMAccountName', 1, 1, 'var' ],
      [ 'UserEmail', 'Email', 'mail', 1, 1, 'var' ],
      [ 'UserCustomerID', 'CustomerID', 'mail', 0, 1, 'var' ],
      [ 'UserPhone', 'Phone', 'telephonenumber', 1, 0, 'var' ],
      #[ 'UserAddress', 'Address', 'postaladdress', 1, 0, 'var' ],
      #[ 'UserComment', 'Comment', 'description', 1, 0, 'var' ],
    ],
  };

#Add the following lines when only users are allowed to login if they reside in the specified security group
#Remove these lines if you want to provide login to all users specified in the User Base DN
#example: $Self->{'Customer::AuthModule::LDAP::BaseDN'} = 'ou=Users, dc=united, dc=net';
  $Self->{'Customer::AuthModule::LDAP::GroupDN'} = 'CN=otrs_allow_C,OU=Users,DC=United,DC=net';
  $Self->{'Customer::AuthModule::LDAP::AccessAttr'} = 'member';
  $Self->{'Customer::AuthModule::LDAP::UserAttr'} = 'DN'
