Yes, I receive the challenge. In fact, after initially spotting the problem, I
implemented:
- (BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection
{
return NO;
}
so in fact, I'm now seeing the challenge on each login attempt.

When I try:
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage]
cookiesForURL:[NSURL URLWithString:@"www.some.url"]];
at application startup I receive an empty array, so it doesn't look like any
cookies are being stored.

Hmmm, and now I can change accounts without problems. I'll test some more, but
the most likely scenario is I was cooked when I was recently testing this.
Thanks for the suggestions Roland. I wasn't aware of NSHTTPCookie and
NSHTTPCookieStorage, so at least I picked up some new info. If I run into
trouble again with this, I'll follow up on this thread.
Cheers,
António
