| =head1 Apache::Authn::Redmine | ||||
| Redmine - a mod_perl module to authenticate webdav subversion users | ||||
| against redmine database | ||||
| =head1 SYNOPSIS | ||||
| This module allow anonymous users to browse public project and | ||||
Jean-Philippe Lang
|
r1321 | registred users to browse and commit their project. Authentication is | ||
| done against the redmine database or the LDAP configured in redmine. | ||||
|
Nicolas Chuche
|
r903 | |||
| This method is far simpler than the one with pam_* and works with all | ||||
| database without an hassle but you need to have apache/mod_perl on the | ||||
| svn server. | ||||
| =head1 INSTALLATION | ||||
| For this to automagically work, you need to have a recent reposman.rb | ||||
| (after r860) and if you already use reposman, read the last section to | ||||
| migrate. | ||||
| Sorry ruby users but you need some perl modules, at least mod_perl2, | ||||
| DBI and DBD::mysql (or the DBD driver for you database as it should | ||||
| work on allmost all databases). | ||||
| On debian/ubuntu you must do : | ||||
| aptitude install libapache-dbi-perl libapache2-mod-perl2 libdbd-mysql-perl | ||||
|

|
r1321 | If your Redmine users use LDAP authentication, you will also need | ||
|

|
r1322 | Authen::Simple::LDAP (and IO::Socket::SSL if LDAPS is used): | ||
| aptitude install libauthen-simple-ldap-perl libio-socket-ssl-perl | ||||

r903 | </Location> | ||
| To be able to browse repository inside redmine, you must add something | ||||
| like that : | ||||
| <Location /svn-private> | ||||
| DAV svn | ||||
| SVNParentPath "/var/svn" | ||||
| Order deny,allow | ||||
| Deny from all | ||||
| # only allow reading orders | ||||
| <Limit GET PROPFIND OPTIONS REPORT> | ||||
| Allow from redmine.server.ip | ||||
| </Limit> | ||||
| </Location> | ||||
| and you will have to use this reposman.rb command line to create repository : | ||||
| reposman.rb --redmine my.redmine.server --svn-dir /var/svn --owner www-data -u http://svn.server/svn-private/ | ||||
| =head1 MIGRATION FROM OLDER RELEASES | ||||
| If you use an older reposman.rb (r860 or before), you need to change | ||||
| rights on repositories to allow the apache user to read and write | ||||
| S<them :> | ||||
| sudo chown -R www-data /var/svn/* | ||||
| sudo chmod -R u+w /var/svn/* | ||||
| And you need to upgrade at least reposman.rb (after r860). | ||||
