beginner problem when installing Oracle 10g personal

[cgreynes]

Hi,

When I installed Oracle 10g in my workstation, I got errors in the Database Configuration Assistant.

1st Error: ORA-12639: Credential retrieval failed.
2nd Error: ORA-03114: not connected to ORACLE

I searched using google and found the details below but still dont know how to fix it.

ORA-12639 Authentication service negotiation failed

Cause: No match was found between the types of authentication services that the client supports and those that the server is using.

Action: Possible solutions:
1. Change the entry in sqlnet.ora that determines which services are to be used.
2. Relink the client with at least one of the authentication service adapters that the server supports.
3. Relink the server with at least one of the authentication service adapters that the client supports.
4. Disable authentication on both the client and server.

I came from MS SQL and starting to learn Oracle. Help would be greatly appreciated.

Thanks
Clark

i searched online and one person said to set SQLNET.AUTHENTICATION_SERVICES= (NONE). after this, i did not get the error above. don't know if this is the right way to do it but i'm glad that i can continue my self-study on oracle.
