Oracle Clients Cannot Resolve Service Names in AD After OracleContext is Created (Doc ID 361528.1)

Last updated on JANUARY 12, 2009

Applies to:

Oracle Net Services - Version: 9.2.0.1.0 to 10.2.0.1.0
Microsoft Windows (32-bit)

Symptoms

After successfully creating an OracleContext and adding a Net Service name via NetMgr, client  applications still cannot use AD to resolve their service name.

ORA-12154 : TNS could not resolve the connect identifier specified 

A tnsping might yield:  TNS-03505: Failed to resolve name

An anonymous search using ldapsearch against the OracleContext fails, but when the search is performed with credentials it retrieves the data.
