[Error Code] The permissions may be wrong on your proxy file [Definition] If the permissions on your proxy file are too lax (for example, if others can read your proxy file), Globus Toolkit clients will not use that file to authenticate. [Possible Solutions] 
You can "fix" this problem by changing the permissions on the file or by destroying it (with grid-proxy-destroy) and creating a new one (with grid-proxy-init). Important: However, it is still possible that someone else has made a copy of that file during the time that the permissions were wrong. In that case, they will be able to impersonate you until the proxy file expires or your permissions or end-user certificate are revoked, whichever happens first.
