HP b2600 Administration Manual page 149

An <action> applies to all <operations> that follow it, until the next <action> is encountered. Thus,
"irwad" means "ignore read and write, allow delete."
GetProperty and RotateProperties may do multiple operations (r and d, or r and w). If different actions
apply to the operations, the most severe action is applied to the whole request; there is no partial request
execution. The severity ordering is:
allow < ignore < error
Thus, if the <perms> for a property are ired (ignore read, error delete), and an untrusted client attempts
GetProperty on that property with delete=True, an error is returned, but the property value is not.
Similarly, if any of the properties in a RotateProperties do not allow both read and write, an error is
returned without changing any property values.
Here is an example security policy file.
