Yet another incorrectly filed ticket.

See the end of the traceback message:

Please update the option account-manager.hash_method in trac.ini.

We could hardly be more explicit about how to fix this issue, couldn't we?

Sorry, but this is showing to me very clearly, that at the reporters side not much effort has been put into research about proper configuration. Especially make sure in your trac.ini you have

acct_mgr.pwhash.htdigesthashmethod = enabled

comment:3 in reply to:  2 ; Changed 12 years ago by anonymous

I am receiving the same error as rjollos, but via a different method. I receive the error when clicking "Reset Passwords" on the "Manage User Accounts" page. I am using HtPasswdStore rather than SessionStore or SvnServePasswordStore. Enabling the pwhash.htdigesthashmethod component as suggested does not solve the problem. The documentation doesn't say anything about using pwhash in conjunction with HtPasswdStore, or at least not that I was able to find.

Here are my account-manager settings:

allow_delete_account = false
force_passwd_change = true
htpasswd_hash_type = crypt
password_file = <redacted>
password_store = HtPasswdStore
persistent_sessions = true
refresh_passwd = False
user_lock_max_time = 0
verify_email = true
acct_mgr.admin.accountmanageradminpages = enabled
acct_mgr.api.accountmanager = enabled
acct_mgr.htfile.htpasswdstore = enabled
acct_mgr.web_ui.accountmodule = enabled
acct_mgr.pwhash.htpasswdhashmethod = enabled

I made the prior post; apologies for not leaving contact information. I assume I should reopen the ticket as well...

No offense intended, but what's the issue with following advice given by a rather trustworthy plugin? I don't get that, really.

If you're curious enough, or security conscious or both, a look into changelog, the commit log or some closer looks at the source will tell you, that the reset password process has dramatically changed, and that using a modified SessionStore for the interim reset passwords has been part of the current solution to prevent DOS attacks by false faked request request from a third party.

Nevertheless I appreciate your hint about this being not obvious in current wiki documentation. I'll try to improve relevant places (AccountModule and SessionStore) before closing this ticket again.

#10406 has been closed as a duplicate. The patch by Jun Omae seems a bit unrelated, but deserves further investigation, even if not applying to current trunk anymore.

comment:7 Changed 12 years ago by Steffen Hoffmann

(In [12097]) AccountManagerPlugin: Send notification for password reset only after storing it, refs #8770.

Unsuccessful attempts to store a new password will no longer yield misleading user notification about unsaved, effectively invalid passwords.

Beware though, that the password reset procedure has been changed to prevent premature password invalidation, so the old password will continue to exist until next successful login for that user account anyway.

(hand-added, because it seems to not have landed here even with appropriate commit message)

(In [12398]) AccountManagerPlugin: Releasing version 0.4, pushing development to acct_mgr-0.5dev.

Availability of that code as stable release closes #874, #3459, #4677, #5295, #5691, #6616, #7577, #8076, #8685, #8770, #8791, #8990, #9052, #9079, #9090, #9139, #9246, #9252, #9547, #9618, #9676, #9843, #9852, #9940, #10023, #10028, #10123, #10142, #10204, #10276, #10397, #10412, #10594, #10625 and #10644.

Some more issues have been worked-on, yet without confirmed resolution, refs #5464 (for JiraToTracIntegration), #8927 and #10134.

And finally there are some issues and enhancement requests showing progress, but known to require more work to resolve them satisfactorily, refs #843, #1600, #5964, #8217, #8933.

Thanks to all contributors and followers, that enabled and encouraged a good portion of this development work.
