One my Oracle DB user has encrypted password set to all Zeros. I extracted the encrypted password from user DDL and I see all zeros.
ALTER USER "xxxx" IDENTIFIED BY VALUES 'S:000000000000000000000000000000000000000000000000000000000000';
What does this mean and how did it happen ? We had DB patching during that time. The user is not able to connect. He gets invalid username/ password error.
DB Version : 126.96.36.199 ( 19c Enterprise Edition )
