The authentication element can have the following values:
- none
- Specifies that no authentication is required to run the web script. This is the default value if the authentication level is not explicitly specified.
- guest
- Specifies that at least guest level access is required to run the web script.
- user
- Specifies that at least a user account is required to run the web script.
- admin
- Specifies that at least an adminstrator account is required to run the web script.
The authentication element also has the following attributes:
- runas (optional)
- The runas attribute allows a web script developer to state that the
execution of a web script must run as a particular repository user, regardless of who
initiated the web script.
This is useful where the behavior of the web script requires specific permissions to succeed. Due to security concerns, the runas attribute is only available for web script implementations placed into the Java classpath.
The user to run as is specified through the runas attribute of the <authentication> element of the web script descriptor. For example:
<webscript> <shortname>Example Run As Usage</shortname> <url>/runas</url> <authentication runas="admin">user</authentication> </webscript>
Here, the web script still requires a user to authenticate before execution; however, the web script executes as the admin user. Repository features, such as auditing, still reflect the user who initiated the web script.
