Configure NTLM for Opera and Safari and chrome

I am trying to make an existing intranet application that used to work only in 开发者_开发百科IE 7, a browser independent application. In firefox(I set network.automatic-ntlm-auth.trusted-uris) and IE(inbuilt) I was able to configure it. The question is how to configure NTLM in Safari/Opera/Chrome.

---

Firefox works with below setting:

1. Type about:config in address bar
2. Type ntlm in search and change below value:
   • network.automatic-ntlm-auth.trusted-uris = .yourdomain.com,localhost
3. Type negotiate in search and change below values:
   • network.negotiate-auth.delegation-uris = .yourdomain.com
   • network.negotiate-auth.trusted-uris = .yourdomain.com

With the latest Opera in the url bar type about:config then do a search for NTLM
