You haven't had any success getting the registration link to display? Or do you have the link displaying, but the registration page doesn't seem to be working?

I get a working registration page in a setup that follows the Cookbook steps:

http://trac-hacks.org/wiki/CookBook/AccountManagerPluginConfiguration#HtPasswdStore

So I suspect it has something to do with using HttpAuthStore.

 

This is Red Hat Enterprise Linux 6.3, Trac 0.12.4 from the EPEL RPM repository and (currently) the AccountManager plugin 0.4.2 (though I've been trying this since version 3.something with no success).

I have a global trac.ini file that each project inherits.  I'm using the HTML form for logins and that works.  The relevant sections (I think) are below.  The Web admin pages show everything enabled here as enabled.  I must be missing something simple, but I have no idea what it is.

TIA for any assistance.  Let me know if I need to supply more information.

[account-manager]

# password_file = /var/www/svn-control/coin.pwd

# password_store = HtPasswdStore

authentication_url = /authFile

password_store = HttpAuthStore

 

 [components]

acct_mgr.admin.* = enabled

acct_mgr.admin.accountmanageradminpanel = enabled

acct_mgr.api.* = enabled

acct_mgr.api.accountmanager = enabled

#acct_mgr.htfile.* = enabled

acct_mgr.htfile.abstractpasswordfilestore = disabled

acct_mgr.htfile.htdigeststore = disabled

acct_mgr.htfile.htpasswdstore = diabled

acct_mgr.http.httpauthstore = enabled

acct_mgr.pwhash.htdigesthashmethod = disabled

acct_mgr.pwhash.htpasswdhashmethod = disabled

acct_mgr.register.* = enabled

acct_mgr.register.registrationmodule = enabled

acct_mgr.register.emailverificationmodule = enabled

acct_mgr.notification.accountchangelistener = enabled

acct_mgr.web_ui.* = enabled

acct_mgr.web_ui.accountmodule = enabled

acct_mgr.web_ui.loginmodule = enabled

acct_mgr.web_ui.registrationmodule = enabled

trac.web.auth.loginmodule = disabled

You can simplify this quite a bit:

 [components]

acct_mgr.admin.* = enabled

acct_mgr.api.* = enabled

acct_mgr.htfile.* = disabled

acct_mgr.http.httpauthstore = enabled

acct_mgr.pwhash.* = disabled

acct_mgr.register.* = enabled

acct_mgr.notification.accountchangelistener = enabled

acct_mgr.web_ui.* = enabled

trac.web.auth.loginmodule = disabled

I've tried your config, and I get the following warning in the logs:

10:33:17 AM Trac[register] WARNING: RegistrationModule is disabled because the password store does not support writing.

I'm not sure what is going on yet, but could you check your logs and look for that message? See (1) if you need more info on that.

From http://trac-hacks.org/wiki/AccountManagerPlugin/AuthStores#HttpAuthStore

"Note: This password store does not support listing/adding/removing users or changing passwords."

I really don't know much about HttpAuthStore, but you might consider changing to a different password store.

Good point, thanks Ryan. This store indeed doesn't support writing user
account changes, so no new accounts as well, just authentication.

For making registration work, you'd indeed need a r/w-capable password
store.

Basically it's HTTPAuth wrapped to make it usable via HTTP login form,
including true log-out capability.

Thanks for the suggestion.  I tried switching back to HtPasswdStore (which I had used before, also without success regarding registration), but the problem persists.  

I followed the example on the AccountManager page and here, so the relevant parts of trac.ini are now:

[account-manager]                                                               

password_file = /var/www/svn-control/coin.pwd                                   

password_store = HtPasswdStore                                                  

htpasswd_hash_type =     

 [components]                                                                    

acct_mgr.admin.* = enabled                                                      

acct_mgr.api.* = enabled                                                        

acct_mgr.htfile.* = disabled                                                    

acct_mgr.htfile.htpasswdstore = enabled                                         

# acct_mgr.pwhash.htpasswdhashmethod = enabled                                  

acct_mgr.register.* = enabled                                                   

acct_mgr.notification.accountchangelistener = enabled                           

acct_mgr.web_ui.* = enabled                                                     

trac.web.auth.loginmodule = disabled

Logins work with the usual httpd pop-up, but still no Register link.  The wiki page now displays this at the top:

 Warning: Error with navigation contributor "AccountModule"

which I have not seen before with any configuration I've tried.  When I attempt to log in, the log file reports

2013-01-07 01:21:20,477 Trac[chrome] ERROR: Error with navigation contributor AccountModule: AttributeError: Cannot find an implementation of the "IPasswordHashMethod" interface named "HtDigestHashMethod".  Please update the option account-manager.hash_method in trac.ini.

So I'm not sure I'm any closer.

[mjs]

Solved the error message by including both

acct_mgr.pwhash.htpasswdhashmethod = enabled                                    

acct_mgr.pwhash.htdigesthashmethod = enabled 

But still no Register link 8^(

No, I'm wrong. Registration is now working.  Thanks everyone for your help.

Does this mean that one can't have both the login form with logouts and the registration capability?

What makes you think so? Of course Login and Register both can happily
co-exist in Trac's meta-navigation menu.

- From previous description of yours I've got the impression that maybe
you've setup your web-server for authentication, but only one is
required, BasicAuth/DigestAuth via web-server or AccountManager's
LoginModule, that provides the Login link you've been asking for, and
that allows to log-out and log-in as another user easily within seconds.
In practice the web-server will probably overrule LoginModule, indicated
by a HTTP auth pop-up like seen i.e. on trac-hacks.org.

Take a look at wiki documentation [1][2], if you're uncertain, an ask
away here for anything that may not be covered by the docs yet.
