Is there requirement of income certificate at the time of filling application form (i.e. Certificate number) for EWS candidates or it will be required after the selection process. Because I want to apply for EWS reservation but I don’t have certificate as if now but later on I’ll be issued what can I do Please reply as soon as possible. Economically Weaker Section (EWS) in India is a subcategory of people belonging to the. The eligibility to get the EWS certificate is not only purely based on annual. Came out in many ways including the form of anti-reservation agitations.
Learn how to create and reference a certificate validation callback method so that you can make EWS Managed API requests to an Exchange server.
By default, versions of Exchange starting with Exchange 2007 SP1 use self-signed X509 certificates to authenticate calls from EWS. When you are using the EWS Managed API, you need to create a certificate validation callback method; otherwise, EWS Managed API requests will fail. If you are using the Autodiscover service, the call to the EWS Managed API Autodiscover method will fail with an AutodiscoverLocalException error. If you are using a web-generated web service proxy, you might also have to create a validation callback method, depending on how the proxy is created.
Prerequisites for creating a validation callback method
To set up to validate a server certificate, ensure that the following are true:
Your Exchange server is using a self-signed certificate for EWS. If the administrator has installed a valid certificate that traces to a root certificate, you do not need to create a validation callback method.
You are creating a managed application that includes a reference to the following required .NET Framework namespaces:
- System.Net
- System.Net.Security
- System.Security.Cryptography.X509Certificates
Example: Callback method to validate a server certificate for the EWS Managed API
The following code example shows how to create an X509 certificate validation callback method for the EWS Managed API. This method will validate an X509 certificate and only return true when either of the following criteria are met:
- The certificate is valid and traces back to a valid root certificate.
- The certificate is valid and is self-signed by the server that returned it.
Important
The certificate validation callback method in this example provides sufficient security for development and testing of EWS Managed API applications. However, it might not provide sufficient security for your deployed application. You should always make sure that the certificate validation callback method that you use meets the security requirements of your organization.
You use the ServicePointManager class in the .NET System.Net namespace to hook up a validation callback method by setting the ServerCertificateValidationCallback property. You can use code similar to the following code example to set the ServerCertificateValidationCallback property.
Next steps
After you have created the validation callback method for the EWS Managed API, you can use the Autodiscover service to get connection points and user and domain settings from an Exchange server. For more information, see the following articles:
