Apologies for the delayed response...
I am using the Oracle in OraClient12 ODBC connector.
I had researched this further with Oracle. A related issue documented suggests changing the password to upper case. This actually worked, but makes no sense to me or the DBA. The Oracle documentation is attached.
Error: "Oracle ODBC Ora ORA-01017: invalid username/password; logon" When Attempting To Create An ODBC Connection To An Oracle P6 EPPM Schema (Doc ID 1581032.1)
