Hello all,
I'm experiencing this issue with build 10.6.3.25 on Windows 7 x64 inside a corporate environment. As I am in a corporate environment it means that any solution suggesting credentials being stored in a plain text password file are not going to be approved due to the outragous risk imposed by such.
In our environment, Group Policies set the iTunes proxy settings for Internet Explorer and iTunes then reads these settings but seems to have no ability to save the credentials for later use.
A rather simple solution to stop this issue occurring at program launch would be to implement an iTunes feature to not connect to the iTunes store on startup. Asking for authentication when you're actually trying to do something which requires internet connectivity isn't as much of an issue; however users being asked immediately, repeatedly to authenticate at application launch is terrible design.
I'm curious if anyone has managed to progress any further towards a resolution of this issue as I would be very keen on discussing it.
I'm rather shocked at the complete lack of Apple representation within this thread (and the entire discussions forums) as this is clearly a bug with iTunes. If no one has found a magic solution (hinting at The Magic Engineer here) for this bug, I'll officially report it to Apple and see what they have to say for their lack of action.
Thanks in advance!
Lucidite.
