是否有任何 Web 界面可以分配 trac、SVN、SFTP 的权限?
右侧列出的服务可以轻松编辑不与控制台交朋友的人?
Trac admin web-UI already supports permission groups and assigning allowed actions to both groups and individual users.
For setting more fine grained permissions you'll want something like FineGrainedPageAuthzEditorPlugin (general), for repositories TracSvnAuthzPlugin (simple) or SvnAuthzAdminPlugin (advanced).
If do not use existing authentication infrastructure of your web-server you may want user/account administration inside Trac too. Look at AccountManagerPlugin. A common way is to let it manage a central file in htpasswd or htdigest format, that can be used by multiple services, even across several Trac environments, if you like.
trac.ini 可以通过 Web 界面使用TracIniAdminPanelPlugin进行编辑。我不知道其他的网络接口。我认为这是因为有很多方法可以设置授权配置。
