Trac SvnAuthzAdminPlugin not showing users

I'm using Trac v0.12.2 with the SvnAuthzAdminPlugin and AccountManagerPlugin. I'm sharing a HtDigest auth file between Trac and Apache/Svn.

trac.ini

[trac]
authz_file = /trac/svnaccess
repository_type = svn

[account-manager]
password_store = HtDigestStore
password_file = /trac/trac.htdigest
htdigest_realm = TracRealm

[components]
acct_mgr.web_ui.LoginModule = enabled
trac.web.auth.LoginModule = disabled
acct_mgr.admin.AccountManagerAdminPages = enabled
acct_mgr.htfile.HtDigestStore = enabled
acct_mgr.pwhash.htdigesthashmethod = enabled
svnauthz.* = enabled

[svnauthzadmin]
show_all_repos = true

For some reason, all users show up in the AccountManagerPlugin's Users menu, but only the TRAC_ADMIN user shows up in the SvnAuthzAdminPlugin select box for adding users to a group. Everything else works exactly 开发者_开发问答the way it should and I can manually add entries to my svnaccess file. I know it's something small because I've had it working before with, what I thought was, the exact same configuration.

Any help/suggestions are appreciated.

Based on this ticket filed against the svnauthz plugin, it looks like this may be a limitation in the plugin itself. According to a comment on that ticket:

The list of users that is shown comes from the list of users (or groups) in Trac that have been assigned at least one permission.

So, if you want to give one person specific access in svn authz, they need to have at least one permission explicitly granted to them in the Trac permissions; they can't have their only permissions come from Trac group membership.

Try explicitly assigning a permission to a few user accounts and see if they show up in the list. If that seems to work, then you may want to consider re-building the plugin from source and applying one of the two patches described in that ticket (the second patch listed seems more straightforward IMO).
