apache2 config - subversion alias

[Mike Dewhirst <mi...@dewhirst.com.au>]

I'm trying to troubleshoot an Apache 2.0.53 configuration issue** and 
discovered a subversion warning in my SuSE 9.1 boot.msg. Subversion 
appears to be working fine so maybe this isn't a problam at all - just a 
blind alley.

In any case, when I originally set up subversion, I had to tweak the 
subversion.conf mercilessly to get svn working properly. I probably 
destroyed something so ... the relevant config stuff is below.

Any advice appreciated

Thanks

[Mon Nov 14 10:00:17 2005] [warn] The Alias directive in 
/etc/apache2/conf.d/subversion.conf at line 3 will probably never match 
because it overlaps an earlier Alias.

** The Apache2 problem is that I can't get Basic Auth to work on an 
ordinary directory unrelated to subversion. Basic auth actually works 
for the repositories but not elsewhere. I am posting on the apache list 
with that issue but just in case my subversion config tweaks have caused 
it - I thought I'd better ask here too.

I'm don't use Apache enough to call myself an expert, but my experience 
has been that anytime I use the <Location> directive I will never need 
an Alias.  The <Location> directive is the only thing that is necessary 
here because Subversion through Apache is not a true physical filesystem 
access method.  It is creating more of a web service via the mod_dav_svn 
protocol. 

For more info on the specifics of <Directory> and <Location> tags see 
http://httpd.apache.org/docs/2.1/sections.html.

I would recommend dropping the mod-alias section of your config, and 
move all the <Directory> configuration options to the <Location> tag.  
The only thing that is not necessary is the -FollowSymLinks Option as 
that is not supported in <Location> directives.  But you are already 
disabling it anyway...
