Hi,

Anyone knows how to create a user and applying the password of another user, without the dba knowing the actual password? I am not even sure if this is ever possible.

Let me know your thoughts.

Thanks!

Well the DBA can create a user account (user2) with another user's password (user1), but user1 needs to let user2 know what the password is.

create user user2 identified by values '<insert_user1_hashed_password_from_dba_users_table>';

Thanks, ebrian. But I believe this is not possible. The hash value for the password is generated using the combination of the user's name and password... therefore, if I use the same hash value from user1 to user2, in the end, the actual password will be different as the user name is different. I am not sure if I have explained myself clear but it's something to that effect.

Yes indeed, the password is a hash between the username and password.

Sorry, I overlooked that since I've always just used that process to connect as a particular user and then change that password and then change the password back to the old value.

Thanks guys, It looks like there is no other way but have the users reset the password on the new user ID.
