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.


Dc x521 gateway problems
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.


Dc x521 gateway to do

  • Implement heuristic approaches

  • Optimise

    • By changing sequence of searches

    • By implementing time-outs in ldap searches

  • etc.
