System users are users who have all function and access privileges in a database and who have the required privileges in ARIS Administration. System users can be created by the system administrator (user system) or by another system user.
The system user system is created automatically. This user has full access to all databases of a tenant. The name system cannot be changed. A system user should immediately change the password manager in ARIS Administration to prevent unauthorized access. The function and access privileges of system users cannot be changed at database level. To withdraw privileges from a system user, another system user must disable (Create system user for a database, How to make a user a system user) the System user check box on the user's Function privileges properties page in ARIS Architect. As a result, the user's privileges can be changed. After this, the user has no access privileges.
The system user system assumes the administrator role of the system administrator and has all function and access privileges in all databases of a tenant. Authorized persons can use this emergency user to log in to any database, even if you are using an external system, such as LDAP, for authentication.
The name system cannot be changed. The System user check box for this user (Function privileges properties page in ARIS Architect) cannot be disabled either. You should immediately change the password manager to prevent unauthorized access.
To avoid problems, you should create (Create system user for a database, How to make a user a system user) additional system users. Having more than one system user can avoid problems, for example, if one system user has forgotten his password. If you forgot the passwords of all your system users, the full range of functions is no longer available and full data access is no longer possible.
