Set security attributes

Different operations on the Module Database require different access permissions. See Module Database security permissions. This topic describes how to view or modify access permissions for module database objects (modules, PIunits, heading sets, and headings).

Note: For all Data Archive servers, the possible levels of access are read and write. The possible access rights string can be "r", "w", "r,w" or "" (null). Note that there is no level for deny, as there is in Windows.

1. Right-click the object in the tree, and then click Edit to open the Edit/View dialog box for the selected object.

2. Next to the Access Rights field, click to open the Edit/View Security Attributes dialog box. This dialog box is different for different versions of Data Archive:

   • For Data Archive versions 3.4.380 and later it shows the list of identities/users/groups that have defined access permissions for the selected object. Select an identity, user, or group to see its access permissions. You can add or remove identities, users, and groups using the Add and Remove buttons.

     

   • PI Server versions earlier than 3.4.380 use the owner/group/world model for access permissions. Each object can have an owner, which must be a PI user and a group, which must be a PI group. You can set access permissions for the owner, access permissions for the group, and the access for everyone else (called world access). You can also change the owner or group assigned to that object.
