If you want to access the "HERA-B only" documents, you are asked for a username and a password. This authorisation has nothing to do with any other existing computer account, this username and password exists only for this WWW server and none other will work.
If you are a member of the HERA-B Collaboration, but you do not know a valid username with the correct password, please try to find somebody who knows one at your institute.
No password has changed since the server was set up in 1994. That means, if your password does not work, you propably misspelled it.
/herab/in the path of the filesystem and hence in the URL you see e.g. in the "Location:" field of Netscape.
In case, you want to protect the documents you provide yourself on
this server, the answer is the same: Just create a subdirectory named
herab and put the documents there.
