We are on DSpace 5.8 and have always used internal (i.e
PasswordAuthentication) until now. I've tried enabling LDAP based auth as
follows:
1. In /opt/dspace/config/modules/authentication.cfg set:
plugin.sequence.org.dspace.authenticate.AuthenticationMethod = \
org.dspace.authenticate.LDAPAuthentication
2. Configured /opt/dspace/config/modules/authentication-ldap.cfg as follows:
enable = true
autoregister = true
provider_url = ldap://130.123.96.53:389/
id_field = cn
object_context = ou=clients,dc=massey,dc=ac,dc=nz
search_context = ou=clients,dc=massey,dc=ac,dc=nz
email_field = mail
surname_field = sn
givenname_field = givenName
search.anonymous = false
search.user = cn=ITS LDAP read-only
agent,ou=System,ou=Clients,dc=massey,dc=ac,dc=nz
search.password = <<REDACTED>>
When I log onto our Dspace site with URL /ldap-login then I get the branded
LDAP page, but as soon as I submit I get the traceback provided below.
Using Wireshark, I can see that the DSpace server isn't trying to connect
to our LDAP server. However if (on the same server) I make use of the OS
command line utility "ldapsearch" then an LDAP bind and query is
successful, i.e.
ldapsearch -x -h tur-ldap.massey.ac.nz -b dc=massey,dc=ac,dc=nz will
succeed.
Can someone help me to narrow down the fault ? Am I possibly missing a JAR
?

Happy to provide any further info.
With Thanks,
