Proxy Login Popups on Mavericks I have updated my Mac OS  from Snow Leapord to Mevericks recently. I work behind proxy and I have set proxy for network and saved creadentials in Keychain too.
Still I get annoying system prompts for logging into proxy too many times.
Any solution to get rid of the Proxy login Popups ?
EDIT
I did following steps

deleted proxy credentials from keychain List item
removed the same from Proxy Settings
Added  proxy settings again ( without credentials )
tried to access google from safari it prompts for crdentials ( twice - maybe for http and https connections as I am adding proxy for both ) -- After above prompts I can see my credentials saved in kechain as well for proxy
Still can not access google from safari, can access same from Firefox / chrome ( they have seperate prompt for login ), even can access itune store from iTunes. (iTunes asked me for keychain access of proxy )
removed https proxy and kept only http, now I can not Access iTune Store so added the same again

Here are my keychain attributes for proxy

Name : 127.0.1.1 (vishal.kardode)
Kind : Internet Password
Account : vishal.kardode
Where : http:// 127.0.1.1:80 ( for https proxy its https://... )
Comments : default

Added space between &quot;http://&quot; and &quot;127.0..&quot; as it was not allowing to post
EDIT2
The Issue Persists, now I can not conect to iTunes Store either ( using iTunes )
every time I open Safari or iTunes I get the prompt, every time keychain gets updated as I login using the prompt but not able to connect to https://google.com or iTunes Store. Surprisingly I can connect to other https site
Here is screenshot of the proxy authentication prompt

I have changed the ip of proxy server in above post to 127.0... . Actual ip starts with 172...
Quick question first, are you setting the proxies manually or are you getting the settings via Auto Discovery or an Automatic Proxy Configuration (APC) URL?

If you are setting them manually then you should be able to select Proxy Server requires password and enter the correct credentials there.



If you are getting them as an APC URL then you may have a problem with that particular keychain. Using the Keychain Access utility look in both your login and iCloud keychains and delete any you find for the the proxy server.

Now you should be able to save your credentials properly.
