Subject [jira] Created: (JCR-286) Error in jcr-server Webdav HTTP header - DAV Explorer won't log in

Error in jcr-server Webdav HTTP header - DAV Explorer won't log in
------------------------------------------------------------------

         Key: JCR-286
         URL: http://issues.apache.org/jira/browse/JCR-286
     Project: Jackrabbit
        Type: Bug
    Reporter: Peter Darton
    Priority: Minor


At present, DAV Explorer won't log in to the JCR WebDav servlet - it doesn't even ask for
a username & password.  (Neither the Microsoft WinXP WebDAV & Novell's NetDrive were
as fussy and were happy to log in)
Using Ethereal, I compared the traffic for a valid Slide WebDav login compared to a JCR WebDav
login.

I've now found and fixed the problem on my local build, and I've now got DAV Explorer to work
with JCR Webdav.  Here's a description of the bugfix:

In jackrabbit/contrib/jcr-server/server/src/java/org/apache/jackrabbit/server/AbstractWebdavServlet.java,
there is a public static final String DEFAULT_AUTHENTICATE_HEADER.
This is currently set to "Basic Realm=Jackrabbit Webdav Server".

This is not a valid string for use in this context as it is in breach of RFC2617 for 2 reasons:
1) "Realm" should be "realm"
2) "Jackrabbit Webdav Server" should be in quotes, i.e. "\"Jackrabbit Webdav Server\""

According to http://www.ietf.org/rfc/rfc2617.txt, a valid challenge would be:
   WWW-Authenticate: Basic realm="WallyWorld"
Note that "realm" is not capitalised and "WallyWorld" has been enclosed in quotes (the "WWW-Authenticate:
" string is held elsewhere in the Java code and is correct)


In other words, AbstractWebdavServlet.java line 82, which currently reads:
    public static final String DEFAULT_AUTHENTICATE_HEADER = "Basic Realm=Jackrabbit Webdav
Server";
should be changed to read
    public static final String DEFAULT_AUTHENTICATE_HEADER = "Basic realm=\"Jackrabbit Webdav
Server\"";
