DBMS Authentication
Ingres now allows DBMS level authentication in addition to the other supported methods (which include operating system authentication, installation passwords, and Kerberos authentication). The DBMS authentication feature removes the need to add an operating system user every time a new user needs to access a database.
For details, see DBMS Authentication in the Security Guide, the CREATE USER, ALTER USER, and CONNECT statements in the SQL Reference Guide, and the Connectivity Guide.
