4.2 Managing Security
A user must have a login account to connect to the Postgres server. Use the Login Role dialog (shown in Figure 4.2) to add a new login role or manage the properties of an existing login role on a registered server.
To add a new login role, right click on the Login Roles node (located beneath the selected server in the Postgres Enterprise Manager node of the tree control), and select New Login Role from the context menu.

To modify the properties of an existing login role, right click on the name of a login role in the tree control, and select Properties from the context menu. To delete a login role, right click on the name of the role, and select Delete/Drop from the context menu.
Use the Group Roles node (located beneath the name of each registered server in the PEM tree control) to create and manage group roles. Options on the context menu provide access to a dialog that allows you to create a new role or modify the properties of an existing role. You can find more information about creating roles at:
When you register a server for monitoring by PEM, you can specify a Team role that will be associated with the server. A Team role is a group role that can be used to allow or restrict access to one or more monitored servers to a limited group of role members.

To open the New Group Role dialog and create a team role, right-click on the Group Roles node of the tree control and select New Group Role… from the context menu. When the New Group Role dialog opens, use the fields provided to specify the properties of the team role. For more information about creating a Team role, see the PEM Installation Guide, available at:
A role must be granted sufficient privileges before accessing, executing, or creating any database object. PEM allows you to assign (GRANT) and remove (REVOKE) object permissions to group roles or login accounts using the graphical interface of the PEM client.
By default, PEM displays only group roles on the Privileges tab of the Properties dialog. To instruct the PEM client to include login roles in the User/Group list on the Privileges tab, navigate through the File menu, to open the Options dialog. Select the UI Miscellaneous control node, and then check the box next to Show users for privileges to include login roles on the Privileges tab.
The PEM client also contains a Grant Wizard (accessed through a schema node of the tree control) that allows you to manage many object permissions at once.
