I'm trying to change the firefox config network.automatic-ntlm-auth.trusted-uris; so I can use SSO for everyone on my companies internal page.
First I found this: manage Firefox via group policy
I tried this on the network.automatic-ntlm-auth.trusted-uris; but it won't work since this specific config is locked. The pref however is set in the pref.js in the Firefox profile folder but SSO is not working.
I tried to use lockPref in the user.js but it won't work.
I have found no entries containing another lockPref("network.automatic-ntlm-auth.trusted-uris",...). Neither in the profile folder nor in the program folder.
Any ideas how to unlock this specific pref? Also it seems like a change of users.js will not change the prefs.js right after the first start of FF. Instead it took me more than 1 restart of FF to see the changes of users.js in the prefs.js.
