[launchd-dev] The mysterious SHAuthorizationRight key

Hi there, Running 10.5.1, I see the following in my syslog: com.apple.launchd[1] (org.apache.httpd): Unknown key: SHAuthorizationRight Upon investigating the launchd plist for httpd there is a declaration: <key>SHAuthorizationRight</key> <string>system.preferences</string> Unfortunately I have been unable to find launchd documentation describing this key. Can you please advise; I like to know what my syslog messages mean. :-) Cheers, -C
