Hi Sub,

it is possible to store user information (e.g. name, password, database name, ...) in a special file (.XUSER.62 in the HOME directory of the OS user - Unix/Linux) resp. in the registry (Microsoft Windows). The data can only be accessed by the operating system user who owns the data.
Please also check SAP Note 39439. Do you have such a file present?

Additionally: Which MaxDB version is in use? Maybe it is a bug explained in SAP Note 1444241.

Best regards,
Andreas
