EUS Connections Intermittently Fail with "ORA-28045: SSL authentication between database and OID failed", ldapbind on SSL Port Fails with "SSL handshake failed" (Doc ID 1908523.1)

Last updated on JULY 01, 2016

Applies to:

Oracle Internet Directory - Version 10.1.4.3 and later
Information in this document applies to any platform.

Symptoms

Two-node installation of Oracle Internet Directory (OID) (e.g., 10g server0 and server1, behind a load balancer (LBR) of hostname "oid0.mydomain.com") integrated with Enterprise User Security (EUS) on Database (DB) 11g.

EUS used to work but suddenly fails with:

ORA-28045: SSL authentication between database and OID failed

When invoked via:

 

Ldapbind succeeds against lbr host "oid0.mydomain.com" on non-ssl port  and with ssl mode "U 1" (encryption only, no certificates) on ssl port.
Ldapbind fails against lbr host "oid0.mydomain.com" on ssl port using ssl mode "U 2" (server authentication) with "SSL handshake failed".
Ldapbind fails against lbr host "oid0.mydomain.com" on ssl port using ssl mode "U 3" (client and server authentication) with "SSL handshake failed".


The issue is intermittent - both EUS authentication and ldapbinds fail, then suceed, then fail again, and so on.
