    Connect as SYS user- possible without PWD??- OS User not in DBA group

    Connect as SYS user- possible without PWD??
    Dear All,



    Right now I have a different kind of a problem (opposite to the one that I faced before). In one of the databases here, Iam able to connect as sys user with SYSDBA privs even though that user is not even in the group DBA ( I checked the group the user is assigned to with the ID command). But for anyother Oracle user, login is possible with the password.

    SUN OS 5.8

    Oracle 9.0.1

    Looking forward to hear further from you, a solution to this problem.

    Regards,

    K.Diwakar

    Post the exact sequence of steps followed verbatim for the 2 users quoted, right from the OS login.

    BTW, post also the result of 'groups' for both the users.

    HTH.

    Dear Gnanaraj,

    Pls find the steps below. Iam new to SUN/UNIX. Kindly point out how I should proceed..

    Regards,

    K.Diwakar



    $ id
    uid=1003(oasisadm) gid=102(oasis)
    $ export ORACLE_SID=oasis
    $ echo $ORACLE_SID
    oasis
    $ sqlplus

    Hey Pandi,

    Here is the output:

    $ cat /etc/group |grep dba
    dba::400asisadm,op,crdadm
    $ cat /etc/passwd | grep oasisadm
    oasisadm:x:1003:102:Oasis Admin User:/oasis/ist73:/bin/ksh




    but as you say, the problem is solved. We can see the oasisadm user on DBA group also. The command:


    $ whoami
    oasisadm


    $ id -a
    uid=1003(oasisadm) gid=102(oasis) groups=102(oasis),1(other),2(bin),3(sys),4(adm),5(uucp),6(mail),7(tty),400(dba)
    $



    We can see that OASISADM belongs to group OASIS as well as DBA. Sorry for Iam new to UNIX and just getting on slowly. and as I could not look for DBA in the command:

    $ id
    uid=1003(oasisadm) gid=102(oasis)

    I proceeded with the post. Thank u Gnanraj and Pando. Looking forward for continued support from you all.

    Regards,

    K.Diwakar
