Hi,
Just for me to understand... sometime it works and sometime it does not work with same user aneil2?
>From the log I can see that you probably have Basic Authorization Headers enabled, are you sure you do not type user/password in the browser credentials dialog? can you please add KrbMethodK5Passwd off to the apache configuration to make sure it is not prompted? To clear this, if you use firefox go to History->Clear Recent and select only Active Logins.
What I see is that aneil2 cannot be located, and fallback to Basic Authorization Headers is probably performed, and in these the aneil2 is specified without @profile suffix (as expected) and it fails.
