We have a perfectly fine LDAP server setup that things like ReviewBoard uses for
authentication. However, Hudson does not.

Example session when querying the user "chainsaw" via ldapsearch:
-----------------------------------------------------------------
ldapsearch -h 192.168.1.103 -x -D "cn=Manager,dc=domain,dc=name" -W uid=chainsaw
Enter LDAP Password: somethingdarkside

1. extended LDIF
   #
2. LDAPv3
3. base <> with scope subtree
4. filter: uid=chainsaw
5. requesting: ALL
   #

1. Jens B\C3\A4ckman, People, domain.name
   uid: chainsaw
   homeDirectory: /home/chainsaw
   loginShell: /bin/bash
   objectClass: inetOrgPerson
   objectClass: posixAccount
   objectClass: top
   much-more-stuff-here-but-snipped

1. search result
   search: 2
   result: 0 Success

1. numResponses: 2
2. numEntries: 1

Hudson config file, the important parts:
-----------------------------------------------------------------
<version>1.319</version>
<securityRealm class="hudson.security.LDAPSecurityRealm">
<server>domain.name</server>
<rootDN></rootDN>
<userSearchBase></userSearchBase>
<userSearch>uid=

</userSearch>
<managerDN>cn=Manager,dc=domain,dc=name</managerDN>
<managerPassword>somethingdarkside</managerPassword>
</securityRealm>

Hudson backtrace:
