I seem to have discovered that something that I thought was possible  
might  
actually not be so.

I have a scenario where I would like users from specific IP ranges to  
have to go  
through the authentication procedure and others not to.

I thought for sure this would work:  
if ( $remote\_addr != range ) {  
auth\_basic “bla”;  
auth\_basic\_user\_file users.conf;  
}

However, I’m discovering that if you do a test of this config that nginx  
does  
not like the auth\_basic directive in the if condition. Is this the  
correct  
behaviour? Is there a way around it? Is there some way to emulate what I  
want?

Yes.

location / {  
satisfy\_any on;

```
allow 192.168.1.0/32;
deny all;

auth_basic "bla";
auth_basic_user_file users.conf;

```

}
