i can't log onto my Grid either as "sys" through the web console. but, i've never tried until just now. is there a reason why you want to log in as "sys"?When i do log on as an administrator and go to setup -> Administrators, i can see "sys" but i've never done anything with it. I've logged in as SYSMAN then created my own Administrators.Ya, there's definitely no way in the Console logon to do SYS/<password> AS SYSDBA HTHLyall ----- Original Message ----- From: "Balakrishna Y" To: sundarmahadevan82@xxxxxxxxx Cc: Oracle-L@xxxxxxxxxxxxx Subject: Re: any junk password works for sys Date: Fri, 18 Sep 2009 14:16:12 +0530 Hi, Did you set this parameter SQLNET.AUTHENTICATION_SERVICES = (NONE) in sqlnet.ora.

I have a couple of questions to ask: I tried to logon to http://host.domain:4889 as "sys" user but it says "error: login operation failed" I try to logon with "sys as sysdba", then i get "this user is not a valid enterprise manager administrator" I thought it might be a problem with password file and hence renamed the old orapwemrep and created a new orapwemrep with orapwd utility but then when i logon with "sys as sysdba" I get "your username and/or password are invalid" Also when I logon to the database through sqlplus, any junk password for user sys works. I remember removing dba administrator group on windows servers long back to fix a similar issue. But I do not know how to fix this on my linux box. Btw, my remote_password_file is set to exclusive. Please note that I am able to logon as "system" to http://host.domain:4889 Any help is greatly appreciated.
