This document explains the installation steps for the PSP.  Here's an overview of how it was configured:

1.  The PSP writes data to the directory installed on grinnell.
2.  Group objects are created for each Grouper group (excluding the etc folder) in ou=grouper,ou=group,dc=alaska,dc=edu.
3.  The "bushy" structure is used.

== Prepare LDAP ==

1.  Create the base DN that we're using to store groups in LDAP.

{{{
[oracle@grinnell ~]$ ldapmodify -a -h localhost -p 1389 -D "cn=directory manager" -W
Enter LDAP Password:
dn: ou=grouper,ou=group,dc=alaska,dc=edu
objectClass: organizationalUnit
ou: grouper
aci: (targetattr="*") (version 3.0; acl "Grouper Write Access";allow (add,delete,read,write,search,compare) (userdn="ldap:///uid=grouper03,ou=resource,dc=alaska,dc=edu" and ip="127.0.0.1");)

adding new entry "ou=grouper,ou=group,dc=alaska,dc=edu"

}}}

== Install PSP ==

1.  Download and copy the PSP to /tmp/ on grinnell. The tarball is located at  http://www.internet2.edu/grouper/release/2.1.4/grouper.psp-2.1.4.tar.gz.

2.  Extract and copy files.  Note that we're using the generic LDAP example configuration as a starting point.

{{{
[root@grinnell ~]# cd /srv/grouper
[root@grinnell grouper]# ls
grouper.api-2.1.4  grouper.api-2.1.4.tar
[root@grinnell grouper]# mv /tmp/grouper.psp-2.1.4.tar.gz .
[root@grinnell grouper]# gunzip grouper.psp-2.1.4.tar.gz
[root@grinnell grouper]# tar xf grouper.psp-2.1.4.tar
[root@grinnell grouper]# cp /srv/grouper/grouper.psp-2.1.4/lib/custom/* /srv/grouper/grouper.api-2.1.4/lib/custom/
[root@grinnell grouper]# cp /srv/grouper/grouper.psp-2.1.4/conf/psp-example-grouper-to-ldap/psp* /srv/grouper/grouper.api-2.1.4/conf/
[root@grinnell grouper]# cp /srv/grouper/grouper.psp-2.1.4/conf/psp-example-grouper-to-ldap/ldap.properties /srv/grouper/grouper.api-2.1.4/conf/
}}}

== Configure PSP ==

1.  Find the following properties in /srv/grouper/grouper.api-2.1.4/conf/ldap.properties and update the values.

{{{
edu.vt.middleware.ldap.ldapUrl=
edu.vt.middleware.ldap.bindDn=
edu.vt.middleware.ldap.bindCredential=
edu.vt.middleware.ldap.baseDn=dc=alaska,dc=edu
edu.internet2.middleware.psp.groupsBaseDn=ou=grouper,ou=group,dc=alaska,dc=edu
edu.internet2.middleware.psp.peopleBaseDn=ou=people,dc=alaska,dc=edu
}}}

2.  In the file /srv/grouper/grouper.api-2.1.4/conf/psp-services.xml, replace the Service element with id=ldap with the following:

{{{
<!-- commenting out
  <Service
    id="ldap"
    xsi:type="psp-ldap-target:LdapTarget"
    logSpml="true"
    ldapPoolId="ldap"
    ldapPoolIdSource="grouper">
    <!-- A <ConfigurationResource/> is required to instantiate the <Service/>, so supply a do-nothing resource. -->
    <ConfigurationResource
      file="/edu/internet2/middleware/psp/util/empty-bean.xml"
      xsi:type="resource:ClasspathResource" />
  </Service>
-->

  <Service
    id="ldap"
    xsi:type="psp-ldap-target:LdapTarget"
    logSpml="true"
    ldapPoolId="ldap"
    ldapPoolIdSource="spring">
    <!- - A <ConfigurationResource/> is required to instantiate the <Service/>, so supply a do-nothing resource. - ->
    <ConfigurationResource
      file="/psp-vt-ldap-1.xml"
      xsi:type="resource:ClasspathResource">
      <ResourceFilter
        xsi:type="grouper:ClasspathPropertyReplacement"
        xmlns="urn:mace:shibboleth:2.0:resource"
        propertyFile="/ldap.properties" />
    </ConfigurationResource>
  </Service>
}}}

3.  Create the file /srv/grouper/grouper.api-2.1.4/conf/psp-vt-ldap-1.xml with the following contents.  Be sure to update the password.  Also, note that this is connecting to the directory on grinnell using the non-SSL port 1389.  If this was connecting to a directory on a remote machine, the SSL port should be used.

  </bean>
</beans>
}}}

4.  Find the following properties in /srv/grouper/grouper.api-2.1.4/conf/grouper-loader.properties and update the values.  Properties need to be uncommented.

{{{
changeLog.consumer.psp.class = edu.internet2.middleware.psp.grouper.PspChangeLogConsumer
changeLog.consumer.psp.quartzCron = 0 * * * * ?
changeLog.psp.fullSync.class = edu.internet2.middleware.psp.grouper.PspChangeLogConsumer
changeLog.psp.fullSync.quartzCron = 0 0 5 * * ?
}}}
