#818 closed defect (worksforme)

Cannot find an implementation of the "IPasswordStore" interface named "HtPasswdStore".

Reported by: ccosenti@… Owned by: mgood
Priority: normal Component: AccountManagerPlugin
Severity: major Keywords:
Cc: Trac Release: 0.10

Description

Running Win 2k Server

  • Trac 0.10
  • Python 2.4
  • Apache 2.2

The stock authentication worked fine. Could not get the login to work. The WebAdmin portion worked fine when I was using Apache authentication.

I am not real familiar with python, so perhaps I am missing a Python module? If so, it was not clear from the instructions.

When I turned off Apache authentication and used acct_mgr.web_ui.LoginModule = enabled, Trac threw the following error.

My Config:

acct_mgr.web_ui.LoginModule = enabled
acct_mgr.web_ui.RegistrationModule = enabled
acct_mgr.api.AccountManager = enabled


[account-manager]
; configure the plugin to store passwords in the htdigest format:
password_format = htpasswd
; with Trac 0.10 use this instead:
password_store = HtPasswdStore

; the file where user accounts are stored
; the webserver will need write permissions to this file
; and its parent folder
; NOTE: THIS IS A VALID FILE AND WORKS WITH APACHE AUTHENTICATION
password_file = f:\XMLBUGS\htpasswd

You also need to enable "acct_mgr.htfile.HtPasswdStore" component before you can use it (I've updated the Wiki to try to make this more clear).

Also, you should only use one of "password_format" or "password_store", which is why it says "with Trac 0.10 use this instead:".

Thanks! That fix did it.

Sorry if I missed it in the original wiki.

(no authentication stuff)

Thanks for you help

You have used "enable" in several places, which should instead be "enabled". Also, the password_store, password_file, and htdigest_realm settings should be in the [account-manager] section, not under [components].

Things were working perfectly yesterday but today I get an error. I didn't change anything on the server.

I get a similar error:

Just reinstalled trac as I couldn't find a way to fix it & couldn't wait longer to get a response.
