Symptoms

When configuring an external LDAP authenticator provided, different ways to establish user group membership are seen and they use distinct number of LDAP connections. This affects application authentication performance.

Following scenarios were tested for the LDAP user "myUser" which belongs to five groups (Group1, Group2, Group3, Group4 and Group5).

1. Logged into the WLS Administration Console to obtain the groups for "myUser." . Clicked on Security realms > myrealm > Users&Groups > myUser > Groups and found these LDAP queries on the ldap_ATN log file.

LDAP queries to retrieve group information are causing a delay in the authentication process, so main goal is to reduce the number of these calls that establish the user principal.
