Subversion configured for Windows Active Directory HTTPS
If you want to set up a subversion server on a windows machine that recognizes users from Microsoft Active Directory and uses secure http (https) to communicate with clients you can use the following setup as a template for your configuration.
Steps to follow:
1) Download and install Apache 2.2 + open SSL from http://www.apache.org. Do use Apache 2.2 instead of Apache 2.0 if you want to connect to Active Directory
2) Download the apache 2.2 binary compatible version of svn from http://svn.tigris.org
3) Copy all dll's and modules (.so files) from subversion/bin directory to the apache2.2 /modules directory
4) Copy an existing svn repository or create a new repository
cd "c:\program files\subversion\bin" svnadmin hotcopy //computer/share/subversion/repositories/repo1 c:/subversion/repositories/repo1
svnadmin create c:/subversion/repositories/repo1
5) Create a authorization file: svn.authz
### This file is an example authorization file for svnserve. ### Its format is identical to that of mod_authz_svn authorization ### files. ### As shown below each section defines authorizations for the path and ### (optional) repository specified by the section name. ### The authorizations follow. An authorization line can refer to a ### single user, to a group of users defined in a special [groups] ### section, or to anyone using the '*' wildcard. Each definition can ### grant read ('r') access, read-write ('rw') access, or no access ### (''). [groups] group1 = harry,sally group2 = romeo,julia group3 = sally,julia [/] * = r @group1 = rw
6) Create a SSL certificate
- Openssl.exe included with this version of Apache 2.2 does not seem to be configured well on windows. In order to create a certificate, you need a well configured version of openssl. For this example configuration of subversion with https, file Openssl-0.9.7e-Win32.zip combined with file openssl.conf were downloaded from support.etouch.net
- run the following commands
openssl req -config openssl.cnf -new -out svn.example.com.csr openssl rsa -in privkey.pem -out svn.example.com.key openssl x509 -in svn.example.com.csr -out svn.example.com.cert -req -signkey svn.example.com.key -days 1000
- copy the resulting *.cert and *.key files to the apache2.2/conf directory
7) Edit apache/conf/httpd.conf
LoadModule dav_module modules/mod_dav.so LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so LoadModule ldap_module modules/mod_ldap.so LoadModule ssl_module modules/mod_ssl.so <VirtualHost _default_:443> SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile conf/svn.example.com.cert SSLCertificateKeyFile conf/svn.example.com.key #<FilesMatch "\.(cgi|shtml|phtml|php3?)$"> # SSLOptions +StdEnvVars #</FilesMatch> #<Directory "C:/Program Files/Apache Group/Apache2/cgi"> # SSLOptions +StdEnvVars #</Directory> SetEnvIf User-Agent ".*MSIE.*" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 #redirect /repos to /repos/ RedirectMatch ^(/repos)$ $1/ <Location /repos/> DAV svn # SVNPath c:/subversion/repositories/repo1 SVNParentPath c:/subversion/repositories SVNListparentPath on Order allow,deny Allow from all AuthType Basic AuthBasicProvider ldap AuthzLDAPAuthoritative off AuthName "svn.example.com" AuthzSVNAccessFile c:/subversion/repositories/svn.authz #at least one of your domain servers listens on port 3268 (besides default ldap port 389) #use the server that listens on port 3268 if you have more than one AD server.

8) Apply ldap patch for MS-AD
When a Microsoft Active Directory times out, it sends a TCP RST instad of a TCP FIN to the client. There is a workaround for this MS AD bug in Apache mod_ldap, see http://www.apachelounge.com/forum/viewtopic.php?t=1995 or download http://www.anneb.dds.nl/httpd-2.2.6_ldappatch_win32_vc6.zip Replace apache modules mod_lap.so and mod_authnz_ldap.so with the files from the downloaded zip file. This configuration allows you to add more than one repository in directory c:/subversion/repositories. All repositories are listed in the browser using URL https://svn.example.com/repos. User names and passwords are validated against Active Directory. Standard svn clients can not browse the list of repositories. Instead you should use the full path to a particular repository, for instance https://svn.example.com/repos/repo1.
9) Binary files cannot be easily merged. The lock-modify-unlock versioning model seems to be the only appropriate model for these type of files. Follow the instructions in [Setting up lock-modify-unlock This description also includes client and server side configuration to accommodate for the lock-modify-unlock model for binary files.
9) Force users to set svn:needs-lock property on new binary files
Binary files cannot be merged. Versioning should follow the lock-modify-unlock model. You can force using this model for binary files following the description on how to setup Automatic lock-modify-unlock.
