Lighttpd

You have configured access control for $HTTP["url"] =~ "^/webdav(?:/|$)". Good. In the auth.require within that block, you can put a match for "/webdav/matt_files" with "require" => "matt" before the "" => ( ... )

Thank you for your answer ! I try to understand the syntax, but i'm quite lost.. as I said, i'm a newbie here !

would it be something like that ?

@  $HTTP["url"] =~ "^/webdav(?:/|$)" {
      # block 2
        alias.url                      = (
            "/webdav" => "/media/stoc_serveur/webdav",
        )
        dir-listing.activate           = "enable" 
        webdav.activate                = "enable" 
        webdav.is-readonly             = "disable" 
        webdav.sqlite-db-name          = "/var/run/lighttpd/lighttpd.webdav_lock.db" 
        auth.backend                   = "htpasswd" 
        auth.backend.htpasswd.userfile = "/var/www/mdpwebdav.shadow" 
        auth.require                   = (
            "^/webdav/matt_files(?:/|$)" => (
                "require" => "matt",
            ),
            "" => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "valid-user",
            ),
        )

Close. You should include "method" and "realm" in "^/webdav/matt_files(?:/|$)" => ( "require" => "matt", ),

I did not succeed in matching the url, i was trying with that stuff, but every valid user has access to the 'MAtt_files' folder

     $HTTP["url"] =~ "^/webdav(?:/|$)" {
        # block 2
        alias.url                      = (
            "/webdav" => "/media/stoc_serveur/webdav",
        )
        dir-listing.activate           = "enable" 
        webdav.activate                = "enable" 
        webdav.is-readonly             = "disable" 
        webdav.sqlite-db-name          = "/var/run/lighttpd/lighttpd.webdav_lock.db" 
        auth.backend                   = "htpasswd" 
        auth.backend.htpasswd.userfile = "/var/www/mdpwebdav.shadow" 
        auth.require                   = (
            "^MAtt_files(?:/|$)" => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "matt" 
            )
            "" => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "valid-user" 
            )
        )
    }

So i came up with that ugly solution :

$HTTP["url"] =~ "^/webdav/famille(?:/|$)" {
    alias.url = ("/webdav/famille" => "/media/stoc_serveur/webdav/famille")
    dir-listing.activate = "enable" 
    webdav.activate = "enable" 
    webdav.is-readonly = "disable" # (default)
    webdav.sqlite-db-name = "/var/run/lighttpd/lighttpd.webdav_lock.db" 
    auth.backend = "htpasswd" 
    auth.backend.htpasswd.userfile = "/var/www/mdpwebdav.shadow" 
    auth.require = (
        "" => ( "method" => "basic",
                             "realm" => "webdav",
                             "require" => "valid-user" ),
        )
}

$HTTP["url"] =~ "^/webdav/MAtt_files(?:/|$)" {
    alias.url = ("/webdav/MAtt_files" => "/media/stoc_serveur/webdav/MAtt_files")
    dir-listing.activate = "enable" 
    webdav.activate = "enable" 
    webdav.is-readonly = "disable" # (default)
    webdav.sqlite-db-name = "/var/run/lighttpd/lighttpd.webdav_lock.db" 
    auth.backend = "htpasswd" 
    auth.backend.htpasswd.userfile = "/var/www/mdpwebdav.shadow" 
    auth.require = (
        "" => ( "method" => "basic",
                             "realm" => "webdav",
                             "require" => "user=matt" ),
        )
}

It seems to work as i wished, but i can understand this is not optimal.
I'd prefer your solution, though. Any advice ?

Please read my prior post more carefully.

Close. You should include "method" and "realm" in "^/webdav/matt_files(?:/|$)" => ( "require" => "matt", ), or, if the case-sensitive URL contains uppercase "^/webdav/MAtt_files(?:/|$)"

I'm sorry if i bother you, I have tried with that :

    $HTTP["url"] =~ "^/webdav(?:/|$)" {
        # block 2
        alias.url                      = (
            "/webdav" => "/media/stoc_serveur/webdav",
        )
        dir-listing.activate           = "enable" 
        webdav.activate                = "enable" 
        webdav.is-readonly             = "disable" 
        webdav.sqlite-db-name          = "/var/run/lighttpd/lighttpd.webdav_lock.db" 
        auth.backend                   = "htpasswd" 
        auth.backend.htpasswd.userfile = "/var/www/mdpwebdav.shadow" 
        auth.require                   = (
            "^/webdav/MAtt_files(?:/|$)" => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "user=matt",
            ),
            ""                           => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "valid-user",
            ),
        )

After the modifications, i just restart the lighttpd service :
systemctl restart lighttpd.service

The webdav share is working but every valid user has acces to MAtt_files, e.g. dav://loic@serveur2nous.local/webdav/MAtt_files can read/write the folder

However, the solution i posted earlier keeping 2 webdav definitions works, i can go ahead with that.

Thanks for your help, sorry to be such a noob.

Sorry. auth.require takes strings for prefix match, not regex.

        auth.require                   = (
            "/webdav/MAtt_files/" => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "matt" 
            )
            "" => (
                "method"  => "basic",
                "realm"   => "webdav",
                "require" => "valid-user" 
            )
        )
