I am trying to develop a custom plugin. Below is my auth plugin plist. However, the mechanism marked as privileged is not being triggered by macOS. If I remove the privilege, it gets called. Any pointers on this? TestPlugin:MyLogin and TestPlugin:MyUser,privileged are my custom plugins. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>class</key> <string>evaluate-mechanisms</string> <key>comment</key> <string>Login mechanism based rule.
