Hi everyone,
I am configuring a DSpace 1.6.0 instance to authenticate users to my
LDAP server. I believe I have the necessary configuration options in
dspace.cfg specified correctly, but if I add
org.dspace.authenticate.LDAPHierarchicalAuthentication to my
Authentication stack, I receive a NullPointerException. If I use the
regular org.dspace.authenticate.LDAPAuthentication method, my logins do
not work.
My relevant bits of dspace.cfg:
ldap.enable = true
ldap.provider_url = ldaps://ldap.unb.ca/
ldap.id_field = uid
ldap.object_context = dc=unb,dc=ca
ldap.search_context = dc=unb,dc=ca
ldap.email_field = mail
webui.ldap.autoregister = true
ldap.search_scope = 2
ldap.search.user = uid=authentication,dc=unb,dc=ca
ldap.search.password = #########
For Hierarchical authentication, I receive the following stack trace:
java.lang.NullPointerException
at
org.dspace.authenticate.LDAPHierarchicalAuthentication$SpeakerToLDAP.getDNOfUser(LDAPHierarchicalAuthentication.java:381)
at
org.dspace.authenticate.LDAPHierarchicalAuthentication.authenticate(LDAPHierarchicalAuthentication.java:212)

org.dspace.app.xmlui.utils.AuthenticationUtil.Authenticate(AuthenticationUtil.java:139)
at
org.dspace.app.xmlui.aspect.eperson.LDAPAuthenticateAction.act(LDAPAuthenticateAction.java:100)
When I switch back to the other method, I see this in dspace.log:
2010-06-24 12:09:36,234 INFO org.dspace.authenticate.LDAPAuthentication

javax.naming.AuthenticationException\colon; [LDAP\colon; error code 32 -
No Such Object]
That's better, but now I am wondering why my LDAP server is returning No
Such Object. OpenLDAP's ldapsearch tool seems to correctly find my
record, using the same command line arguments. I am prompted for my
authentication password for the authenticated search DN and find my
jnugent record.
ldapsearch -W -D uid=authentication,dc=unb,dc=ca -v -x -H
ldaps://ldap.unb.ca "(uid=jnugent)"
Suggestions are appreciated.
Regards,
Jason
