r903 | package Apache::Authn::Redmine; | ||
=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 | ||||
|
r1362 | registred users to browse and commit their project. Authentication is | ||
done against the redmine database or the LDAP configured in redmine. | ||||
|
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 | ||||
|
r1362 | If your Redmine users use LDAP authentication, you will also need | ||
Authen::Simple::LDAP (and IO::Socket::SSL if LDAPS is used): | ||||
aptitude install libauthen-simple-ldap-perl libio-socket-ssl-perl | ||||
|
r903 | =head1 CONFIGURATION | ||
|
r1405 | ## This module has to be in your perl path | ||
## eg: /usr/lib/perl5/Apache/Authn/Redmine.pm | ||||
PerlLoadModule Apache::Authn::Redmine | ||||
|
r903 | <Location /svn> | ||
DAV svn | ||||
SVNParentPath "/var/svn" | ||||
AuthType Basic | ||||
AuthName redmine | ||||
Require valid-user | ||||
PerlAccessHandler Apache::Authn::Redmine::access_handler | ||||
PerlAuthenHandler Apache::Authn::Redmine::authen_handler | ||||
## for mysql | ||||
|
r1401 | RedmineDSN "DBI:mysql:database=databasename;host=my.db.server" | ||
|
r1402 | ## for postgres (there is memory leak in libpq+ssl) | ||
|
r1401 | # RedmineDSN "DBI:Pg:dbname=databasename;host=my.db.server;sslmode=disable" | ||
|
r903 | |||
|
r1401 | RedmineDbUser "redmine" | ||
RedmineDbPass "password" | ||||
|
r1402 | ## Optional where clause (fulltext search would be slow and | ||
## database dependant). | ||||
|
r1401 | # RedmineDbWhereClause "and members.role_id IN (1,2)" | ||
|
r1404 | ## Optional credentials cache size | ||
# RedmineCacheCredsMax 50 | ||||
|
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). | ||||
