  4. DC/X521 gatewaymore heuristic approaches • Adapt the domain part of the DC_DN and put ldap. in front of it and try this LDAP-host. • Go up one or more domain parts and do a SRV-record look-up and/or put ldap. in front of it.

  5. DC/X521 gatewayproblems • Which parts of the DN must/can be translated? • LDAP search takes time. • At this moment all searches are done as anonymous. No SASL, KERBEROS etc.

  6. DC/X521 gatewayto do • Implement heuristic approaches • Optimise • By changing sequence of searches • By implementing time-outs in ldap searches • etc.
