proxy connection question

Hello I can't seem to get syntax correct for connecting thru a Proxy using username and password.

user : test1/test1
proxy : uwg_proxy/proxypass

alter user test1
grant connect through uwg_proxy
authenticated using password;

SQL> connect test1/test1@xxxx;
Connected.

SQL> connect uwg_proxy/proxypass@xxxx;
Connected.

SQL> connect uwg_proxy[test1]/proxypass@xxxx;
ERROR:
ORA-28150: proxy not authorized to connect as client


Warning: You are no longer connected to ORACLE.

SQL> connect uwg_proxy[test1]/test1@xxxx;
ERROR:
ORA-01017: invalid username/password; logon denied

please help.

Thanks,
Bill

ORA-28150: proxy not authorized to connect as client
Cause: A proxy user attempted to connect as a client, but the proxy was not authorized to act on behalf of the client.
Action: Grant the proxy user permission to perform actions on behalf of the client by using the ALTER USER ... GRANT CONNECT command.

Thanks Davey23uk but if you do that then it negates the previous

alter user test1 grant connect through uwg_proxy authenticted using pasword;

I need to have the proxied user supply botht the username and the users database password.

Out of the 4 proxy authentication modes i'm choosing proxy by providing the user name and password.

thanks
Bill
