Hello, I’m running a small shell server for me and my friends and would like every user to have his own [example.com/user](http://example.com/user) web-accessible, password-protected directory not available to other users. Preferably, with authentication against PAM so that one password could be used for all services. Currently, this is the configuration I came up with (no PAM authentication yet): location ~ ^/(.+?)/download(/.\*)  {         auth\_basic       “Restricted”;         auth\_basic\_user\_file  /etc/nginx/htpasswd;         alias /home/$1/download$2;         autoindex on;         include mime.types;         types { }         default\_type application/octet-stream;     } and it works as expected. Now, I tried to separate users’ access (so that any given user had access only to his directory) with the if statements: location ~ ^/(.+?)/download(/.\*)  {         auth\_basic       “Restricted”;         auth\_basic\_user\_file  /etc/nginx/htpasswd;         alias /home/$1/download$2;         autoindex on;         include mime.types;         types { }         default\_type application/octet-stream;         if ($remote\_user != ‘’) { set $hack b; }         if ($remote\_user != $1) { set $hack a$hack; }         if ($hack = ab) { return 403; }     } That caused 404 errors. This is the relevant fragment of the error log: 2010/09/21 23:12:41 [error] 31813#0: \*245 “/home/wmp/download/.1 Hostindex.html” is not found (2: No such file or directory), client: 87.205.146.217, server: domain, request: “GET /wmp/download/ HTTP/1.1”, host: “domain:9900” And this is debug.log: [http://pastebin.com/4wUQkXZH](http://pastebin.com/4wUQkXZH) Nginx was compiled with the following options: –conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid –lock-path=/var/lock/nginx.lock –http-client-body-temp-path=/var/lib/nginx/body –http-proxy-temp-path=/var/lib/nginx/proxy –http-fastcgi-temp-path=/var/lib/nginx/fastcgi  --with-debug –with-http\_stub\_status\_module --with-http\_flv\_module –with-http\_ssl\_module --with-http\_dav\_module –with-http\_gzip\_static\_module --with-http\_realip\_module --with-mail –with-mail\_ssl\_module --with-ipv6 –add-module=/home/wmp/tmp/nginx/nginx-0.7.65/modules/nginx-upstream-fair –add-module=/home/wmp/tmp/nginx/nginx-0.7.65/modules/ngx\_http\_auth\_pam –with-perl=/usr/bin/perl --sbin-path=/usr/sbin –error-log-path=/var/log/nginx/error.log –http-log-path=/var/log/nginx/access.log --with-http\_perl\_module wmp is, obviously, my username Is what I’m trying to do even possible?

An alternative would be to move “if … { set … }” blocks to server level, but it’s not needed here. Maxim D. ---

Nobody said using named captures will help. Use root instead. Maxim D. ---
