When Donna logs in, she will map to the user account specified for her login Donna , even though she is a member of the accouting group with access. MSDE will always try to match a login to an individual account before looking for group membership. Donna can still login to the database if she is a member of the accounting group under Windows.
You cannot remove the dbo user, and you cannot remove a user who owns an object in the current database. Managing Roles Roles are similar to groups in Windows. A user may be a member in more than one role. Before you create custom roles, take a look at the built in roles to see if they might fit your needs.
There are several fixed roles provided by the database engine at both the server level and the database level. We begin to cover these topics in the next section. Server Roles Adding a user to a fixed server role will grant the user all of the permissions associated with the server role. The following table gives the name of each server roles and a general description of the permissions associated with the role.
Fixed Server Role Description sysadmin This is the administrative role. Users in this role can perform any activity on the server. Bulkadmin A bulkadmin can perform bulk inserts to the database. You can add database users to a fixed server role in WDA. Finally, click Add or Edit Logins on the right hand side of the row with the role you want to edit.
The following is a screen shot editing the sysadmin role. Since these are server level roles, not database roles, you must add a login name, not a user name from a database. For example, if Donna still has a valid login we could make Donna a member of the sysadmin group with the following command.
Fixed Database Roles Adding a user to a fixed database role will grant the user all of the permissions associated with the database role for the given database. If an existing database role already has the required permission set for a user, the best solution is to use the fixed database role instead of creating a new role. Finally, click the edit button in the row for the role you want to edit, which will bring you to the following screen where you can check off available users to add to the role.
The Public Role Every database also contains a fixed role named public. Every user in a database is a member of the public role. You cannot remove the public role or remove users from the public role. The permissions assigned to the public role are the default permissions for the database. We will be taking a closer look at roles later in the article.
The current release of Web Data Administrator does not allow you to add custom roles. There are, however, system stored procedures available. You can only create roles at the database level. The only server roles available are the fixed server roles.
You need to remove all members of a role before the procedure returns success. With all users and roles in place we can look at assinging specific permissions to users and roles. Download Microsoft Edge More info. Contents Exit focus mode. Is this page helpful?

The application uses automatically the login name and password on the client computer to login to the MSDE.
In this example, we will be using the mixed mode authentication, because we want to access the database from both Windows applications and Java applications over a network. The username and password will be sent over the network in plain text. In this example, we will not be granting access from the network. Only local applications can access the database. We will be using mixed mode authentication for Java applications.
In this example, we will not grant network access to the database. We will also only grant Win authentication access. This is the most secure setup, and should be used for embedded MSDE applications.
Please remember that anyone with read access to this file can see the system administrator password if this is an issue. The file looks like this:. In this example, we will be using mixed mode authentication, because we want to access the database from both Windows applications and Java applications over a network.
It is possible to reconfigure the authentication mode for an already installed instance of the MSDE, through the registry. Here, you will configure the default port MSDE will be listening on if you want network access. Default is You will use an alias if you do not want to configure all applications to a specific configuration. The client just accesses the alias, and the client utility will map the request to the right configuration. You should not use any of these databases for any application purposes.
They are holy land as far as the applications know it. They are out of reach, simple as that. Create a new database to store your application data. First of all, you must login as a system administrator sa or as a user with dbcreator privileges. Open the osql administration utility and login as system administrator. If you want to list all the databases in the instance, please open the osql utility and do the following query:.
The database can now be moved, backed-up, or you can do whatever you want to do with the files. If you want to list all tables in an instance, please open the osql utility and do the following query:. In this example, we list all tables in the Products database in the myinstance. After creating the user, remember to grant access to the database and the tables for the user.
Please open the osql utility, and do the following query to list all users in the Products database:.
