Last updated on FEBRUARY 23, 2023

Applies to:

Advanced Networking Option - Version and later
Oracle Unified Directory - Version to [Release 11g]
Information in this document applies to any platform.Symptoms

This note is applying to situations when:
#1. Any EUS authentication attempt fails with ORA-28030 (this can happen for single instance databases as well).
#2. When the database is a RAC database and is started with srvctl, the authentication is failing with: ORA-28030. When the database is started with sqlplus, the authentication works as expected.
Full error:

ORA-28030: Server encountered problems accessing LDAP

The first thing to do is to take a trace file for EUS authentication:

KZLD_ERR: failed to get cred from wallet
means that the wallet that is used to authenticate the database to the directory cannot be found.
