Hello!
I'm working on adding WebDAV access to the directories already
accessible via FTP. The layout is fairly simple: the /data/ftp tree
houses the "home" directories of FTP's (virtual) users. I wanted to give
the HTTP users the same experience they get via FTP -- they must login,
and then their top-level directory will be /data/ftp//USERNAME/. No user
should see the full listing of users, nor be able to get into another
user's subtree even by guessing the other username.
To this end I set up the configuration as follows:
DocumentRoot "/data/ftp"
<Directory /data/ftp>
AuthType Basic
AuthName "Foo File-Server"
Require valid-user
AuthUserFile /somewhere/passwd
RewriteEngine on
# Without the below condition, the rewrite rule keeps rewriting
# until "Internal Error". A mystery...
RewriteCond %{ENV:REDIRECT_STATUS} !200
RewriteRule (.*) %{REMOTE_USER}/$1 [L]
</Directory>
<Directory /data/ftp/*>
DAV on
</Directory>
This almost works -- upon going to the site (say,
https://ftp.example.com/), the user is asked to login. He is then served
the content of /data/ftp//USERNAME/, which appears as the top-level
directory in the browser... Great...
However, for some reason, when a DAV-capable client is used (checked
with cadaver and konqueror), a user "wallaby" sees not only the content
of /data/ftp/wallaby, but also an entry (a "collection") named
"wallaby", which is not really there on the server at all (there is no
/data/ftp/wallaby/wallaby). Trying to access that phantom collection
results in an error...
The questions:
1. How do I eliminate the phantom entry from the otherwise perfect
listing? Is its appearance a manifestation of a bug in mod_dav?
2. Is it possible to achieve the same effect (DocumentRoot based on
REMOTE_USER) without mod_rewrite?
3. If the answer to 2. is "no", is there a better way to express what
I want, than the two statements I came up with? In particular,
without the check for REDIRECT_STATUS, I see (in mod_rewrite's
log) continuing rewrites to
/data/ftp/wallaby/wallaby/wallaby/..../wallaby -- until it gives
up and throws a 500...
Thank you very much for any hints. Yours,
-mi
