Hello,

I'm trying to get OS authentication to work for os (Solaris) user padss. I'm going through the steps below:

1. Create OS user padss
2. SQL> show parameter os_authent_prefix

NAME TYPE VALUE
------------------------------------ -------------------------------- ------------------------------
os_authent_prefix string OPS$

3. As Oralcle OS user and sys:

CREATE USER "OPS$padss" IDENTIFIED EXTERNALLY;
GRANT CONNECT TO "OPS$padss";

Both are sucessful.

4. sqlnet.authentication_services = (NTS) in sqlnet.ora

5. log in as os user padss

6. sqlplus /

ORA-01017: invalid username/password; logon denied


Any ideas what is going wrong? I think that I've followed the steps correctly, but clearly I've missed something.

Many thanks
