Issue/Introduction:

We run Web Agent, and when the same user login within the same second, the first tentative fails as the second with the same credentials succeeds :

  This script runs 20 Authentications a minute; 

Why is this happening? How can we fix this? 
 

Cause:

This issue occurs because the Policy Server tries to update a field that the Novell LDAP Server hasn't replicated completely.
 

Environment:

Web Agent R12.52 SP1 CR01 on Apache 2.2 on RedHat 6.6 64 bit; 
User Store on Novell eDir LDAP 8.8.8;
 

Resolution:

Disable "Track successful logins" on the password policies to solve this issue, or tune the LDAP Server replication to cope with the load you put on the environment.
