I have a Apache setting, which contains a DAV svn configuration.
How many groups can mod_auth_mysql pass to Apache for one user? Multiple groups or just one? If just one group is passed, is there a workaround, which makes svn get multiple groups from a mySQL-DB?
Groups are not "passed to Apache". Apache passes the information from httpd.conf or .htaccess file to our module without any checking of parameters. We return whether the login is valid or not - nothing more.
