Environment

Novell SecureLogin
NSL 7.x
SecureLogin installed in ADAM mode
SecureLogin installed in LDS environment

Situation

How does Novell SecureLogin failover work?
How and when does NSL in ADAM mode attempt to connect to a different server?
How does SecureLogin use the Preferred ADAM instances list?

Resolution

Installed in ADAM mode, SecureLogin locates services in the following order:
  1. Last known good ADAM server stored inHKCU\Software\Protocom\SecureLogin\LastSuccessfulADAMConnection

  2. Preferred ADAM instances list stored in HKLM\Protocom\PreferredADAMInstances

  3. Browse using the ADAMSCP list provided by the domain controller. 

(For more details see TID 7940407)

This order is followed both with the initial connection at login time and when the local cache is refreshed.  In other words, in ADAM mode SecureLogin will attempt to connect to an alternate server when it refreshes its cache if the original server is not available.  If no other ADAM server can be located SecureLogin will go into offline mode.
