Proxy credentials not remembered
Dear all
please be assured we have tried many, many things already, including clearing caches, keychains, even fresh installs. We have many, many macs in use at our College, a good number of which suffer from this issue.
The OSX version varies, as does the model of Macbook, but the problem is often the same. The proxy credentials are in the keychain but Safari, App Store, Chrome and other apps do not seem to 'find' them. Alternatively I have tried assigning the proxy settings against HTTP and HTTPS proxy config in the Network System Preference pane, again this does not help. We also have a WPAD file in place so that auto proxy configuration works. And work it does! But sadly, while I can see that the autoconfig is working because the correct proxy server requests credentials, this method still does not cause the Macbook(s) to retrieve and use credentials.
This only seems to affect HTTPS connections, e.g. to https://www.google.co.uk - which of course is Safari's default in-line search.
My only clue so far is a line from the system log on one of the Macbooks, but it doesn't really give a fix - again this line is only generated and the problem seen when attempting to access an HTTPS site:
Nov 11 11:43:19 usersmacbook.ourdomain.com ocspd[411]: Authentication challenge received for "proxy.ourdomain.com:8080", unable to obtain proxy server credential from System keychain.
Please be assured the credentials are most definitely there!
Any help with this issue would be greatly appreciated - particularly with the frightening rate at which the number of students using Macbooks seems to be growing!
Kind regards
Richard
