plist – ‘defaults write com.google.Chrome PasswordManagerEnabled true’ has no effect


‘defaults write com.google.Chrome PasswordManagerEnabled’ has no effect. Neither the contents of /Library/Managed Preferences/com.google.Chrome.plist nor of /Library/Managed Preferences/<username>/com.google.Chrome.plist change. And the corresponding Chrome feature “Offer to save passwords” also stays greyed out / disabled.

How can I fix this? Or: where else are these settings configured?
