Elytron ldaps realm fails if a referral is returned inside a search

XMLWordPrintable

      Elytron LdapRealm fails to follow a referral when ldaps is used (the ThreadLocalSSLSocketFactory is not set).

      With a configuration similar to this one (memberOf is used to locate groups):

      <ldap-realm name="ldap-realm" dir-context="ldap-dir-context" direct-verification="true">
           <identity-mapping rdn-identifier="sAMAccountName" use-recursive-search="true" search-base-dn="DC=redhat,DC=com">
              <attribute-mapping>
                  <attribute reference="memberOf" from="cn" to="Roles" role-recursion="3"/>
              </attribute-mapping>
          </identity-mapping>
      </ldap-realm>
      ...
      <dir-context name="ldap-dir-context" url="ldaps://ldap.redhat.com:636" principal="cn=Administrator,cn=Users,DC=redhat,DC=com" referral-mode="FOLLOW" ssl-context="ldaps-context">
          <credential-reference store="credstore" alias="ldap_password"/>
      </dir-context>
      

      If we have a group (or user) which contains a memberOf of another ldap, something like the following:

      dn: CN=group-with-external-members,OU=Groups,DC=redhat,DC=com
      ...
      memberOf: CN=group-in-another-domain,OU=Groups,DC=lab,DC=redhat,DC=com
      

      The following exception is thrown when a referral is returned for a group that is inside another ldapserver of the forest:

      TRACE [org.jboss.remoting.remote.server] (management task-1) Server sending authentication rejected: java.lang.RuntimeException: ELY01079: ldap-realm realm failed to obtain attributes for entry [CN=group-with-external-members,OU=Groups,DC=redhat,DC=com]

      The reason seems to be that the ThreadLocalSSLSocketFactory is not set when doing a search, so, if a referral is returned the new search created inside the current one has no access to the SSLSocketFactory in the thread local.
