I missed AccountManager plugin setting.
If you enable AccountManager plugin exactly working, Edit your trac.ini like this and restart TOW.
[account-manager]
password_file = c:\TOW\SvnRepo\Projects\trac.htpasswd
password_store = HtPasswdStore
[components]
acct_mgr.admin.accountmanageradminpage = enabled
acct_mgr.api.accountmanager = enabled
acct_mgr.db.sessionstore = disabled
acct_mgr.htfile.abstractpasswordfilestore = disabled
acct_mgr.htfile.htdigeststore = disabled
acct_mgr.htfile.htpasswdstore = enabled
acct_mgr.http.httpauthstore = enabled
acct_mgr.pwhash.htdigesthashmethod = disabled
acct_mgr.pwhash.htpasswdhashmethod = disabled
acct_mgr.web_ui.accountmodule = enabled
acct_mgr.web_ui.loginmodule = disabled
acct_mgr.web_ui.registrationmodule = enabled
trac.web.auth.loginmodule = enabled
This fixes is will be released in TOW 0.2.2 Standard.
