Hi all,

CentOS6.5 \ Apache 2.2.15 \ Perl 5.18.2 \ MariaDB 5.5.39

I followed these instructions for my RT build:
http://binarynature.blogspot.pt/2013/05/install-request-tracker-4.html

I'm very new to RT. I've read up what I could find on CPAN, wiki and 
Google and I'm not quite sure which way to go here. RT is connecting to 
our ldap and a search result is found but the logs in ldap show "closed 
(connection lost)" so I suspect RT isn't seeing\getting the response 
back from LDAP. I have some examples below showing RT's LDAP requests 
with logs as well as the same search run via command line.

The main differences I can see in logs so far is command line test sends 
"scope=2 deref=0" vs RT test "scope=2 deref=2" and also that the RT test 
doesn't unbind and the connection is lost.

Command line: ldapsearch -x -p 389 -h ldap.simons-rock.edu -b 
ou=People,dc=simons-rock,dc=edu "(&(&(uid=*))(uid=wclarke))" mail uid

# extended LDIF
#
# LDAPv3
# base <ou=People,dc=simons-rock,dc=edu> with scope subtree
# filter: (&(&(uid=*))(uid=wclarke))
# requesting: mail uid
#

# wclarke, People, simons-rock.edu
dn: uid=wclarke,ou=People,dc=simons-rock,dc=edu
uid: wclarke
mail: wclarke at simons-rock.edu

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1

# You must install Plugins on your own, this is only an example

#       Plugin( "RT::Extension::SLA" );
#       Plugin( "RT::Authen::ExternalAuth" );

         Plugin( "RT::Authen::ExternalAuth" );
#       Plugin( "RT::Extension::Assets" );
#       plugin( "RT::Extension::Assets::Import::CSV" );
