Using RMS Security
This type of security is available only if your computer has an installed RMS client. A system administrator may be able to provide this. RMS can also be accessed by a tool on the right of the Security ribbon. The service allows you to compile a set of names or groups and specify permissions and prohibitions for each of them, in relation to the current document.
You must provide login authentication to enter the RMS server.
The following rights are available:
Owner - this person has full rights over the document
View - the document may only be viewed.
Print - the document may be viewed and printed.
Modify - the defined user or group may modify the document.
Copy or extract content - part or all of the content may be pasted into other documents .
This is a subset of the permissions offered directly by this panel in Power PDF. When settings are made through RMS, they appear in the relevant Power PDF list items. These permissions travel with the document and will be valid wherever it is opened.
The following methods can be used to apply RMS security settings:
Use a server template - this may have been created by a system administrator.
Use a local template - you can create such a template.
Use a customized policy - you make settings without using a template.
Additional actions are available, such a setting an expiry date for the rights, giving an address where a user may request additional rights and specifying a time limit for license checking (the default is ten days). This determines the length of time a user may use the document off-line. To prevent expiry, the user must reenter the RMS server with the document, so the license is renewed.
