DoesUserHavePermissions is True, even if user has no access!

Hi,

i am using the following line of code to check if user has access to site:

if (siteCollection.RootWeb.DoesUserHavePermissions(currentUser, SPBasePermissions.Open))

I do this inside of RunWithElevatedPrivileges but saving the SPContext User BEFORE RunWithElevatedPrivileges. While i am debugging my solution i see that the "correct" user, which i store into variable currentUser.

But even the user has no access to the site, checking on SPBasePermissions.Open on some Sites gives me True. When i try to open the Site with the User, i get an Error.

I do not use Anonynous-Access anywhere.

Hope that someone has an idea why this happens.

Best Regards
Bog
