Wes,
Your user DN for the admin user is odd. I would expect it included some sort of “ou” component, something more along the lines of:
‘user’ => ‘cn=admin,ou=people,dc=ucsc,dc=edu’,
A couple more questions for you:
-
What kind of LDAP server are you running?
-
Do you have any sort of LDAP browser software on your machine? (ldapsearch is fine, but sometimes a little hard to get going).
That should solve your LDAP DN syntax issue.
Thanks,

Subject: Re: [rt-users] ExternalAuth help needed
I found that I don’t need to define MySQL as an external auth source because, uh, it is not external. I am using the default mysql authentication for rt. So I removed mysql from the ExternalAuthPriority and ExternalInfoPriority arrays.
This quiets some of the more perplexing “Password Encryption” errors, but still leaves me with these similar errors:
For a local rt user:
[Thu Jan 13 21:39:34 2011] [critical]: Search for (ou=group,dc=ucsc,dc=edu=uid=wmodes,ou=people,dc=ucsc,dc=edu) failed: LDAP_INVALID_DN_SYNTAX 34 (/usr/local/rt/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth/LDAP.pm:116)
and for an LDAP only user:
[Thu Jan 13 21:40:27 2011] [critical]: Search for (ou=group,dc=ucsc,dc=edu=uid=rjohnson,ou=people,dc=ucsc,dc=edu) failed: LDAP_INVALID_DN_SYNTAX 34 (/usr/local/rt/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth/LDAP.pm:116)
[Thu Jan 13 21:40:27 2011] [error]: FAILED LOGIN for rjohnson from 128.114.163.50 (/usr/lib/rt/RT/Interface/Web.pm:424)
Here are the config files:
Any configuration directives you include here will override
RT’s default configuration file, RT_Config.pm
To include a directive here, just copy the equivalent statement
from RT_Config.pm and change the value. We’ve included a single
sample value below.
This file is actually a perl module, so you can include valid
perl code, as well.
The converse is also true, if this file isn’t valid perl, you’re
going to run into trouble. To check your SiteConfig file, use
this comamnd:
perl -c /path/to/your/etc/RT_SiteConfig.pm
#Set( $rtname, ‘example.com’);
#Set( $rtname, ‘example.com’);
#Set(@Plugins,(qw(Extension::QuickDelete RT::FM)));
Set(@Plugins,qw(RT::Extension::ExtractCustomFieldValues
RT::Authen::ExternalAuth));
require “/etc/rt/RT_Authen-ExternalAuth.pm”;
Look into the zoneinfo database for valid values (/usr/share/zoneinfo/)
Set( $Timezone , ‘US/Eastern’);
Set( $WebPath , “/rt”);
Set($rtname , “rt.library.ucsc.edu”);
Set($Organization , “rt.library.ucsc.edu”);
Set($Timezone , ‘US/Pacific’);
Set($DatabaseUser , ‘root’);
Set($DatabasePassword , ‘r3c@ll’);
Set($DatabaseName , ‘rt3’);
Set($CanonicalizeEmailAddressMatch , ‘rt2.library.ucsc.edu$’);
#Set($CanonicalizeEmailAddressReplace , ‘library.ucsc.edu’);
Set($RTAddressRegexp, ‘@rt2.library.ucsc.edu$’);
Set($OwnerEmail, ‘rootmail’);
Set($WebBaseURL, "http://rt2.library.ucsc.edu"http://rt2.library.ucsc.edu);
$LogoURL points to the URL of the RT logo displayed in the web UI
Set($LogoURL , $WebImagesURL . “library.gif”);
Set($LogToFile, ‘error’);
1;
and the external auth config:
The order in which the services defined in ExternalSettings
should be used to authenticate users. User is authenticated
if successfully confirmed by any service - no more services
are checked.
Set($ExternalAuthPriority, [ ‘My_LDAP’,
]
);
The order in which the services defined in ExternalSettings
should be used to get information about users. This includes
RealName, Tel numbers etc, but also whether or not the user
should be considered disabled.
Once user info is found, no more services are checked.
You CANNOT use a SSO cookie for authentication.
Set($ExternalInfoPriority, [
‘My_LDAP’
]
);
If this is set to true, then the relevant packages will
be loaded to use SSL/TLS connections. At the moment,
this just means “use Net::SSLeay;”
Set($ExternalServiceUsesSSLorTLS, 0);
If this is set to 1, then users should be autocreated by RT
as internal users if they fail to authenticate from an
external service.
Set($AutoCreateNonExternalUsers, 0);
These are the full settings for each external service as a HashOfHashes
Note that you may have as many external services as you wish. They will
be checked in the order specified in the Priority directives above.
e.g.
Set(ExternalAuthPriority,[‘My_LDAP’,‘My_MySQL’,‘My_Oracle’,‘SecondaryLDAP’,‘Other-DB’]);
Set($ExternalSettings, {
