WSO2 problems after changing Certificate - wso2-api-manager

I have wso2 Identity server in my TEST environment. Team has been using it for some months and lot of users and roles are created.
Recently we have got CA certificates and installed it.
After that we cant add users saying the problem Error while encrypting the Credential for User Name.
Looks like new certificate is the problem.
What is the work around to get around this problem without rebuilding environment?Data is not of much importance.Can clear all the users and roles.
What are the best approaches to over come this?

SQL Server Authentication for Website Login

A client requested that we develop a site for them but instead of the standard ASP.NET authentication or using Active Directory accounts, they would like us to use SQL server accounts for authentication. (That is, an account using SQL Server authentication.)
This website would be exposed to the public Internet and would have users that are not employed by the client and the client's Active Directory is not available in their DMZ.
So I have a few questions on this:
1) Is this a good idea? (Our gut feeling is that it's not.)
2) How should we best go about doing this?
Off the top of my head, the best answer I can come up with for how to do this would be to dynamically build a connection string based off the credentials the user enters in a web form. If the connection is successful, continue to the site. Otherwise, kick them back out to the login page. (And, of course, make sure accounts get logged out in the event of too many failed logins.)
Is there a better way?
Thanks.
1) Is this a good idea? (Our gut feeling is that it's not.)
There are a few problems using this. Notably, you would have to run your application as an escalated user to perform user maintenance-- add/inactivate users, change passwords, etc... Running a web-app with escalated permissions on the database is generally frowned on. If you run this kind of thing outside of your application, then you'll need to get your DBA to run all the user maintenance stuff, which isn't fun. Also, if you have requirements around password complexity, password rotation, etc., you may find SQL Server authentication lacking over what would be available in AD, for example.
2) How should we best go about doing this?
You can easily test credentials provided by attempting to login to SQL Server using the supplied credentials. You can read the connection string from your configuration settings, but then load it into a SqlConnectionStringBuilder object (in System.Data.SqlClientsomewhere), manipulate it to use the supplied credentials, and then connect using the result of that manipulation to test if the credentials were valid.
You would want to use that only for testing your login. After that, you could go back to using your normal connection strings.

WSO2 not working after changing certificates

1)I have my MySQL database in AWS Cloud. Could anything with the database cause problem?
2) If i clear all the tables for WSO2 , will WSO2 work again? If so , which are all the tables to clear.
Suggest any other solutions

Need advice regarding Node.js and WordPress integration

got a Node.js web app (bound to http://my.example.com) and an official app's website (http://example.com) that is on WordPress.
The WordPress site is supposed to handle all the users' administration functions i.e. registration, buying app subscription, affiliate tracking etc.. I use it because it is faster for me now to stick with WordPress rather than develop all this stuff myself. So...
The problem I'm facing now is accessing users' credentials stored in WordPress upon logging in to the app.
My guess is that on getting a login post request from the app, I should fetch the user's data from the WordPress utilizing it's RPC api or query MySQL (don't know what is better yet). If the user exists and the password is correct, the user accesses the app, and if this is a new user, a new record is created in the app's database (MongoDB).
I would like to know are there any better solutions to this problem? I'm concerned about the security of this solution. Is it safe to solve a problem this way? What are the possible pitfalls with it?
Thanks for any reply)

MySQL. AFAIK, WP RPC doesn't support addUser (see below)
If the user exists and the password is correct, the user accesses the app, and if this is a new user, a new record is created in the app's database (MongoDB).
Here's the problem, now you have 2 user database. It'll be better if you add that new user to WP database, so the new user coming from the app should already have the account in the blog.
I would like to know are there any better solutions to this problem?
Split up the user database so it stands on its own. Like StackOverflow and StackExchange family.
I'm concerned about the security of this solution. Is it safe to solve a problem this way? What are the possible pitfalls with it?
Yes. Use a secure connection between node and MySQL if they don't sit on the same box or local network. Use different MySQL user for each app with proper access.

Best way to log users programmatically into a 3rd party website (when OAuth is unavailable)?

I'm working on an asp.net website that needs to store user passwords for another website so that I can retrieve data periodically without requiring the user to keep logging in. I can't imagine how one-way hashes would work in this case since the user isn't going to be re-keying the password every time. I'm assuming I need to encrypt the passwords to store in a SQL Server database and decrypt them when needed. But that's where things get tough for me. The basic infrastructure is a C#/Asp.Net MVC3 website running on load-balanced Azure compute instances and storing data in SQL Azure. I'm not a crypto guy, and I don't want to make a rookie mistake. There seems to be a lot of information out there, but nothing seems clear to me. Even though the data I'm connecting to isn't sensitive, I want to treat my users' information with the same care I want my personal data treated. Any advice on how to proceed would be appreciated.
EDIT:
I certainly understand that storing passwords is not a best practice, but in some cases it is simply unavoidable. I have come across this project, but have not tried it yet: http://securentity.codeplex.com/. It uses a digital certificate on the web server.
Users of the 3rd party site are able to set their data as "public", in which case I wouldn't need to store their password. So I may give users the option of doing that instead.
You should have a look at OAuth and Single Sign-On.
In simple terms: Only an authentication token is sent between the different systems.
You (the site) should never have knowledge about the users passwords. At most you should know the hash of the passwords to your site.
Read the two topics above and you will know how to properly secure your and the "neighbour" site.
Edit
In Short:
The other site (site B) implements OAuth server processes. Your site (site A) implements OAuth client authentication. When requesting user information from site B you redirect the user to site B authentication to allow site A to read information from site B regarding the user. Site B creates a token that site A can use to access the information. This token can be time limited (or not).

How do I configure IIS so that the user's domain credentials are used when connecting to SQL server?

We've recently released the latest version of our intranet application, which now uses windows authentication as standard, and needs to be able to connect to a configured SQL server with the end-user's domain credentials.
Lately we've found that on a couple of customer deployments, although IIS can see the user's domain credentials, it will not pass these on to SQL server. Instead, it seems to use the anonymous account. This is in spite of following all the correct steps (changing the directory security to Win Auth, updating Web.Config to use Win Auth and denying anonymous users).
I've been doing a lot of reading that suggests we need to make sure that Kerberos is in place, but I'm not sure (a) how valid this is (i.e. is it really a requirement?) or (b) how to go about investigating if it's set up or how to go about setting it up.
We're in a situation where we need to be able to either configure IIS or the application to work for the customer, or explain to the customer exactly what they need to do to get it working.
We've managed to reproduce this on our internal network with a test SQL server and a developer's IIS box, so we're going to mess around with this set up and see if we can come up with a solution, but if anyone has any bright ideas, I'd be most happy to hear them!
I'd especially like to hear people's thoughts or advice in terms of Kerberos. Is this a requirement, and if it is, how do I outline to customers how it should be configured?
Oh, and I've also seen a couple of people mention the 'classic one-hop rule' for domains and passing windows credentials around, but I don't know how much weight this actually holds?
Thanks!

This is called the Double-Hop Problem and prohibits the forwarding of user's credentials to third parties. This occurs when they browse from one machine, against a site on another (first hop), and forwarding the credentials to a third machine (second hop).
The problem will not appear if you host IIS and SQL Server on the same machine.
There's alot more technical details published on this at How to use the System.DirectoryServices namespace in ASP.NET, which explains the double-hop issue, and primary and secondary tokens.
To run your application under the user's Active Directory or Windows credentials, ensure these:
the IIS application is set to NOT allow anonymous access
the IIS application uses Integrated Windows authentication
your connection string should have Integrated Security=SSPI to ensure the user's Windows/AD credentials are passed to SQL Server.
i.e. Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;
You state you're not sure "how to go about investigating if it's set up or how to go about setting it up".
For this I'd heartily recommend a tool called DelegConfig. It's a very handy app that you can tell you if kerberos is setup properly.
Unzip it into a directory, configure a virtual directory in IIS to point to it. Browse to the main page and you tell it which backend server you want to allow access to (e.g. UNC, SQL, HTTP etc..) and it tell you its setup correctly or not and explain why.
It even has the abilty to recongiure the kerberos to fix the issue if you so desire (although I've not used this - I'd rather reconfiguire it myself to understand what I've done in future)
I realise this comes too late for your particular problem but thought it worth sharing for others that follow - especially the tools ability to explain why delegation is or is not working. I've found it invaluble.
