HowTo: CentOS 5, Apache 2.2, Subversion 1.5 with ActiveDirectory Authentication

Here's my step by step:

1. Install CentOS 5.2
2. Configure Network and Proxies as needed
   I usually create a login script: /etc/profile.d/login.sh as follows:
   

   function set_proxies() {
    local s
    PROXY_ADDR="http://proxy.example.com:8000/"
    for s in HTTP HTTPS FTP GOPHER NEWSPOST NEWSREPLY\
             NEWS NNTP SNEWSPOST SNEWSREPLY SNEWS\
             WAIS FINGER CSO; do
        export ${s}_PROXY=${PROXY_ADDR}
    done
       for s in http https ftp; do
        export ${s}_proxy=${PROXY_ADDR}
    done
   }
   
   set_proxies
   

3. I installed from the DVD, so yum update to ensure everything is up-to-date.
   
4. Get my mod_authn_sasl rpm:
   wget http://www.one-dash.com/blog/mod_authn_sasl-1.0.2-3.i386.rpm
5. Install it (this should pull down the):
   yum --nogpgcheck localinstall mod_authn_sasl-1.0.2-3.i386.rpm
   
6. Get my sasl-magic-config script:
   wget http://www.one-dash.com/blog/system-saslauthd-active-directory-config.sh
   dos2unix system-saslauthd-active-directory-config.sh
7. Run the script:
   sh system-saslauthd-active-directory-config.sh example.com
8. Change the security level:
   system-config-securitylevel-tui
   Set SELinux to Permissive, Customize and enable WWW and Secure WWW on the firewall
9. Create the sasl2 configuration for apache:
   echo "pwcheck_method:saslauthd" > /usr/lib/sasl2/apache-httpd.conf
10. Now we need to install Subversion 1.5.2:
    wget http://summersoft.fay.ar.us/pub/subversion/1.5.2/rhel-5/i386/subversion-1.5.2-1.i386.rpm
    wget http://summersoft.fay.ar.us/pub/subversion/1.5.2/rhel-5/i386/neon-0.27.2-1.i386.rpm
    wget http://summersoft.fay.ar.us/pub/subversion/1.5.2/rhel-5/i386/mod_dav_svn-1.5.2-1.i386.rpm
    yum install perl-URI
    rpm -i neon-0.27.2-1.i386.rpm
    rpm -i subversion-1.5.2-1.i386.rpm
    rpm -i mod_dav_svn-1.5.2-1.i386.rpm
    
11. Next modify the apache conf file for our subversion repositories: /etc/httpd/conf.d/subversion.conf
    

    # Needed to do Subversion Apache server.
    LoadModule dav_svn_module     modules/mod_dav_svn.so
    
    # Only needed if you decide to do "per-directory" access control.
    #LoadModule authz_svn_module   modules/mod_authz_svn.so
    
    <Location /svn>
     DAV svn
     SVNParentPath /var/www/svn
    
     <IfModule mod_authn_sasl.c>
    
        # Limit write permission to list of valid users.
        <LimitExcept GET PROPFIND OPTIONS REPORT>
           # Require SSL connection for password protection.
           # SSLRequireSSL
           AuthType Basic
           AuthName "EXAMPLE"
           AuthBasicProvider sasl
           AuthSaslPwcheckMethod saslauthd auxprop
           AuthSaslAppname apache-httpd
           AuthSaslRealm example
           Require valid-user
        </LimitExcept>
    
     </IfModule>
    
    </Location>

12. Next, create the subversion projects root and restart Apache:
    mkdir /var/www/svn
    chown -R apache.apache /var/www/svn
    service httpd restart
    
13. At this point you can now create a test repository:
    svnadmin create /var/www/svn/test
    chown -R apache.apache /var/www/svn/test
14. Let's test if subversion is working:
    svn info http://localhost/svn/test
    svn mkdir --username myWindowsUsername --message "a test commit" http://localhost/svn/test/trunk
15. At this point we should have subversion up and running.
