That's a bit of an open ended question.

I would recommend that you look at the book "Professional DotNetNuke Module Programming" by Mitchel Sellers.  There is other good information available at Michael Washington's website, adefwebserver.com.

It would be better to replace the "stock" Membership Provider with a custom version. You may also want to look at the Role and Profile providers, too.

The existing providers will show you how they were set up, and also the functionality that you have to provide.

If you do this, you can guarantee that the higher-level DotNetNuke functionality is not damaged ...

Hi,

I have been developing modules, providers etc. for the last few year for DNN 4 and 5. But when I had to create custom role and membership
providers while using external databases and web services, I ran across a few very annoying "features" that seem to be very hard to bypass.

  • DNN is getting some information from database views, like vw_UserRoles and vw_TabPermissions, which means that if either DNN Users or
    Roles tables are empty, those view query based features and functions don't work.
  • DNN supports only integers as role and user ids, so using guids or other values in an external database is useless, unless you create
    mapping tables and link those ids together in the providers
  • DNN is sometimes querying for roles by (seemingly) hardcoded value(s), like "Administrator" even though the role provider doesn't
    offer a role with that name

Do you have any suggestions as to how to bypass these things, without creating e.g. users and roles to DNN's tables with similar values as
the ones in the external database? It's not a hard job, but it doesn't sound like it should be... checking every time when a user logs in or
someone is adding a new user based tab permission, if that user or that role already exists in DNN's table, and if not, creating them. I
would appreciate if there is some kind of useful solution, instead of these solutions I have found.

No, I don't have any suggestions.  I suspect that you know a LOT more about than I know!  This would possibly be a good item for discussion on the forums intended for developers at DotNetNuke.com, though.

Thank you for your quick answer. I'm not sure about that, how much I know about DNN. Where ever I go, I'm just finding more restrictions I'll ask this same thing from dotnetnuke.com, even I'm not sure how to make myself enough clear or even visible in that mass.

Hi,

I am new to dotnetnuke(version-5.2).

I want to create a custom registration module I have created one and I am using the default dotnetnuke tables to store the data but there are two fields in database(p word and p wordsalt )to store data regarding p word in some encrypted form how to change my own custom module p word field to store values in these fields.

The next problem I am facing is that after submitting the data what to do so that user get loginned to site.

I got an error message("Violation of UNIQUE KEY constraint 'IX_DNN_Users'. Cannot insert duplicate key in object 'dbo.dnn_users'. The statement has been terminated.") when I submit the data in custom registration to store in database How to resolve that.

Another error message("Invalid length for a Base-64 char array.") comes when I try to login via the account that I have created using custom registration

Please Help me.....



Thanx in advance

Since you are new to DotNetNuke, I think that you should first learn a bit about the inner workings before diving in and coding.

DotNetNuke contains methods to create and modify users, and to login the in and log them out.  You should use those, and you should not be directly interacting with the database.

Look at the existing registration and authentication code and understand it.  Hopefully, you'll be able to take that as a base and modify it for your needs.  Whenever possible, create additional modules, etc. rather than replacing code.  If you work that way, you'll be able to upgrade and keep your custom functionality. 

The book "Professional DotNetNuke 4" has a large section that discusses member management.  Mitchel Sellers' book on creating DotNetNuke modules has lots of very useful information.  Michael Washington's ADEFWebServer.com site has lots of information.

All that said ... my recommend would be that you get a copy of Data Springs' Dynamic Registration and Dynamic Login and use those to create your customized registration and login procedures.  You won't be able to duplicate what they have done for the cost of the modules.
