Hello list, we try to configure an Oracle 8i database for SSL without certificates (without wallets - neither server authentication nor client authentication). The 8i Oracle Advanced Security Administrator's Guide states that it also supports this authentication mode: "Neither the client nor the server authenticates itself to the other, thus using the SSL encryption feature by itself " But the doc then describes only how to configure SSL with wallets. So far we added a listener.ora entry for a tcps connection and added an tnsnames.ora entry for that service. And we added a SQLNET.CLIENT_AUTHENTICATION=FALSE to sqlnet.ora. But we still get the error ORA-28759 Failed to open file - which is generated by an attempt to open a wallet which does not exist. It seems we have to disable the server authentication somehow. Any ideas for that? Peter from Bonn --------------------------------- Was denken Sie über E-Mail? Wir hören auf Ihre Meinung.
