[rt-users] ExternalAuth - loading fine but isn't authenticating to LDAP

[Mike Johnson]

Hi Haris,

No go yet.

Kenneth did send some info for me to check out, perhaps it may help you...

Mike,
First off, check to see how you've set $WebExternalAuto. I'm not sure how
that would affect LDAP if it was turned on.
Second, I'll assume you've set your "Plugins" appropriately to include
"RT::Authen::ExternalAuth".
Thirdly, you have to make sure certain LDAP parameters are consistent (ie.
if you're using TLS, etc.).
Below is what we use for our list of parameters:

Set($ExternalAuthPriority,  [ 'My_LDAP' ] );
Set($ExternalInfoPriority,  [ 'My_LDAP' ] );
Set($ExternalServiceUsesSSLorTLS, 1);
Set($AutoCreateNonExternalUsers, 0);

Set(
    $ExternalSettings,
      {
        'My_LDAP' =>
           {
            ‘type’        => 'ldap',
            ‘server’     => 'ldap.lbl.gov’,
            ‘user’        =>  ‘’,
            ‘pass’        =>  ‘’,
            ‘base’        => 'ou=People,o=name of our company,c=US’,
            ‘filter’       => '(&(status that equals active)(|(dicision
code)))’,
            ‘d_filter’   => '(!(|(lblEmpStat=Staff)(lblEmpStat=Guest)))',
            ‘tls’            => 1,
            ‘net_ldap_args’    => [ version => 3],
            ‘attr_match_list’  => ['Name',
                                                  'EmailAddress',
                                                  'RealName',
                                                  'uid'
                                                ],
            ‘attr_map’            =>  {'Name'                  => 'uid',
                                                  'EmailAddress'    =>
'mail',
                                                  'Organization'      =>
‘o’,
                                                  'RealName'           =>
'cn',
                                                  'ExternalAuthId'  =>
'uid',
                                                  'Gecos'
=> 'uid',
                                                  'WorkPhone'         =>
'telephonenumber',
                                                  'Address1'             =>
'lblmailstop',
                                                  'Address2'             =>
'postaladdress’
                                                 }
           }
      }
   );
1;

I don't think the attr_map would affect this, but your match list could.
Anyway, check it all out cause if there are any inconsistencies (like TLS
being used and on), it will fail.
Hope this helps.
