No access to sitemap.xml

I am having the same problem. I updated to the latest dev release this morning and Google Webmaster Tools is reporting a 404 for the sitemap. I cannot view it when I am logged in or as anonymous and the permissions are set right.

@tsi: What do you mean by no access? Do you mean access denied?

@Grinch2171: The only times XML Sitemap returns a 404 error code is when it's not able to create the cache files for the site map content.

Same error here.

Getting access denied at http://www.symantec.com/connect/sitemap.xml

I've verified that the cached version exists:

[kmilleca@191808-prod1 files]$ cd xmlsitemap
[kmilleca@191808-prod1 xmlsitemap]$ ls
xsm-4b39a726.xml

[edit]
I found that I can access the sitemap file if I log out.
Which makes sense.
Search engines will not authenticate before they grab the sitemap file.
I like the idea of caching the file -- very nice touch!

I am setting this report like duplicate; the fact the site map is only accessible to the anonymous user is clearly stated in the project page.
