Creating a reusable user and group management bundle like FOSUserBundle? - symfony

Actually I have five simple projects based on Symfony 2.0. Each project has user management using Doctrine ORM.
Among bundles, User class has very few differences. Bundle1 may add "business name" attribute, Bundle2 may add "inbound communications" relationship. But all share the same well known attributes like "salt", "password", "username", "roles" and so on. And of course some logic for searching users.
Question is what's a reasonable approach to unify the user management? I mean creating a reusable UserBundle. I'm looking for some advice about xml configuration, mapped super classes, services, entity and forms inheritance.
I've looked at FOSUserBundle, it looks a bit complicated for me. I can't fully understand its logic. I don't need templates and views because each of my five bundles handles that. And I prefer to code it by myself.

You're answering your question yourself, embedding the pros and cons.
Pros:
Reusable code makes development faster
Cons:
Reusable code is often more generic and lead to more complicated things to solve problems.
If you're working in a team which often develop projects involving an User Management, then it is totally valuable to make your own.
Most of the released bundles were initially developed for personal use.
If you know you're not gonna work with anything else than Doctrine2 you can bypass the part abstracting the thing to make it work with MongoDb for example.
If you do so, keep in mind that it will be shared amongst other developers while being used by co-workers which use the same technology as you do.
If you're alone, make it fit your needs.

Is possible to mix Symfony2 CMF and the standard distribution?

We're planning a new intranet for our organization. Some part is like a CMS, and there are some custom-made applications.
The Symfony2 CMF distribution looks fine for building the CMS part of the intranet, but other parts like Doctrine, "normal" SQL databases, etc, looks better for the custom-made applications for the intranet.
Because I need common authorization and authentication system for this intranet (against an Active Directory), I supose that I'll get better results building all in only on app. So, can I mix a CMF application with a normal application, and both use the same database (an Oracle DB)?
Yes you can easily mix the CMF with other Bundles. For example the routing allows using both routes from the CMF as well as "static" routes defined in yml files. Also you can easily also add the ORM next to PHPCR ODM. If you use Doctrine DBAL for storage in PHPCR, you can even reuse the same connection configuration with the ORM etc.
In brief yes it is, and I do this in my own Symfony2 project. I combine both SF-SE and SF-CMF bundles.
In fact, with Symfony2 it's very simple (this is just a matter of choosing the most suitable Bundles; SF is a very decoupled framework, which is why I don't plan to migrate to any other solution for the moment), but I'd like to share some of my experience with doing that. Actually the one most important question to think through to make a decision about how to combine both "worlds" is this:
Composer.
After some inquries I found out that since Symfony CMF is (in a way) based on Symfony SE, and not vice versa, it's better to start with the latter, as it contains the most core features (though I did it also in the opposite way, rather not recommended). So just take a SF-SE's composer.json, take a look at bundles from there you need, and then take a look at differences within SF-CMF's composer.json. You should end up with the most suitable set of bundles.
The basic features from these bundles to look-up for are:
MODEL - Doctrine ORM, PHPCR-ODM, or both - if still not sure, don't hesitate to ask a comment, I'll share here my experience furthere.
ROUTING - the primary question here is how flexible routing do you actually need? If not sure, I'd go with standard SF Router, and then possibly replace it e.g. when still on a dev stage.
OUT-OF-THE-BOX CMS FUNCTIONALITY - bundles such as CreateBundle, MenuBundle or MediaBundle may help you building surprisingly fast, but not quite flexible soltions. In general, I ended up without using most of them, and if using, then I mainly take some Interfaces I do implement in my own Bundles (to ensure future compatibility with possible other bundles to be potentially used).
Besides of these above, I created a number of Bridge Design Pattern and Provider Design Pattern solutions to make some bundles working together, to adjust their functionalities, or simply to decouple things.
In programming almost everything is possible. But think about restrictions delivered with CMF (routing for eg.).
Maybe you should consider Standard Symfony with Sonata? I think CMS pages it's only small part of your system and implementation it in standard symfony will take smallest part (and cost) of whole project.

Symfony2 and Frontend & Backend Bundles

Couple of month ago I got a legacy project written on Sf2. I fixed some bugs, and added some new functionality, but still i feel that it was made a little bit clumsy. Well, maybe not just a little :) So, I have a number of questions, how things really should be done in Sf2.
The first thing which is bothering me, is that the Application is separated on Frontend and Backend bundles. The're standing on the same model, and for example entity Book can be seen from FrontendBundle and edited from BackendBundle. In some way this is producing a confusion of abstractions. So my question is - is it right, or wrong, and if wrong how it should be done in appropriate way?
Bundles are components in symfony2 that provides a functionality to your app. The frontend and backend approach has changed in symfony2, the bundles are used instead.
For example, you can create a BookBundle, and put all the functionality regarding to books in that bundle, adding, updating etc. And by configuring the routes, you can redirect all the requests about the book to that bundle.
The main point is, the frontend and the backend about the books resides in same bundle, and only in that bundle(with controllers and entities and repositories and views etc.).
This is the intended usage in symfony2.

Is it considered bad practice calling a provider directly?

I'm implementing a Custom RoleProvider in the .NET Membership-framework. The existing functionally needs a little tweaking, so I want to implemenet my own Public Functions, to invoke around the static Roles-class.
Instead of Object -> Roles -> RolesProvider
I would go Object -> RolesProvider
Would this be considered bad practice? The only alternative with the current databasescheme is to ommit the use of RoleProvider totally, and implement my own custom system for authorization.
Edit: To clarify, I have already implemented a custom MembershipProvider, so the desire to keep working in the Membership-framework is pretty high.
Any time you circumvent part of a framework or customize it in a way that was not intended it could be considered bad practice. It is the intention of the ASP.NET membership provider framework to facilitate access to the current provider through the Roles class.
The danger of 'bending' the framework to suit your needs instead of extending it as intended is this: there may be other areas in the .net framework, configuration or tools around the role membership functionality that make this assumption, and they may no longer make sense after your changes and cause confusion for others involved in your project. The ASP.NET Website Administration Tool is one example of a tool that makes this assumption. If someone were to use this tool after your changes, your role memberships and site could be potentially corrupted as a result.
If you decide to take this approach you should carefully consider what functionality you are adding and ultimately ask yourself it is really necessary. If it is, you may be better off implementing something completely custom instead to avoid confusion.

Implementation of a ASP.NET based portal-like application

There is the requirement, to write a portal like ASP.NET based web application.
There should be a lightweigted central application, which implements the primary navigation and the authentication. The design is achieved by masterpages.
Then there are several more or less independent applications(old and new ones!!), which should easily and independent be integrated into this central application (which should be the entry point of these applications).
Which ways, architectures, patterns, techniques and possibilities can help and support to achieve these aims? For example makes it sense to run the (sub)applications in an iframe?
Are there (lightweighted and easy to learn) portal frameworks, which can be used (not big things like "DOTNETNUKE")?
Many thanks in advance for you hints, tips and help!
DON'T REINVENT THE WHEEL! The thing about DotNetNuke is that it can be as big or as small as you make it. If you use it properly, you will find that you can limit it to what you need. Don't put yourself through the same pain that others have already put themselves through. Unless of course you are only interested in learning from your pain.
I'm not saying that DNN is the right one for you. It may not be, but do spend the time to investigate a number of open source portals before you decide to write your own one. The features that you describe will take 1000s of hours to develop and test if you write them all from scratch.
#Michael Shimmins makes some good suggests about what to use to implement a portal app with some of the newer technology and best practice patterns. I would say, yes these are very good recommendations, but I would encourage you to either find someone who has already done it this way or start a new open source project on codeplex and get other to help you.
Daniel Dyson makes a fine point, but if you really want to implement it your self (there may be a reason), I would consider the following components:
MVC 2.0
Inversion of Control/Dependency Injection (StructureMap for instance)
Managed Extensibility Framework
NHibernate (either directly or through a library such as Sh#rp or Spring.NET
A service bus (NServiceBus for instance).
This combination gives you flexible user interface through MVC, which can be easily be added to via plugins (exposed and consumed via MEF), a standard data access library (NHibernate) which can be easily configured by the individual plugins to connect to specific databases, an ability to publish events and 'pick them up' by components composed at runtime (NServiceBus).
Using IoC and DI you can pass around interfaces which are resolved at runtime based on your required configuration. MEF gives you the flexibility of defining 'what' each plugin can do, and then leave it up to the plugins to do so, whilst your central application controls cross cutting concerns such as authentication, logging etc.

ASP.NET SqlMembership Provider Scalability

I've got an upcoming project that is going to be dealing with 70,000+ users (education). I was wondering if the ASP.NET SqlMembership Provider has been used at such large capacities? Assuming the hardware is there, is there anything special that needs to be done to make it work smoothly? We're doing all the obvious things like separating boxes for databases and applications, but is there anything code wise that I need to watch out for?
I know one site that, owner of this site wrote a brilliant article about asp.net performance(http://www.codeproject.com/KB/aspnet/10ASPNetPerformance.aspx)
On this article there is one subject that author describes a patch about profile provider for higher performance. Please read that section.
Inbuilt SqlMembershipProvider is very reliable and workable. They tightly integrate with FormsAuthentication and Login Controls. So authentication is reliable and it is also quick to implement.
Only problem I see is the complexity of the Database table structure, they are quite tidy and not so straight at first. So you can basically write your own MembershipProvider that will talk to your own users table with more simplistic design and implementation. Also Managing Members on admin is also painful due to table design but in a way it is fairly possible to do so. For these reasons we wrote our own MembershipProvider based on Sql. It's working amazingly and we've had good experience of the same.
If you have a small website or project
you can straight go on with inbuilt
SqlMembershipProvider but for a large
project like yours I'd recommend
writing your own MembershipProvider.
