    C# LDAP SSL connection fails

    I am using the following code to connect to aLDAP server using SSL. The following code will work only if i turn off the SSL flag. Can any one please tell me what am i missing here to do a SSL connection.

    Every time the findAll is called it is saying that

    the server is not operational

    Do i need to provide any NetworkCredentials?

    DirectoryEntry dEntry =null;
    // for anonymous login. supports this.
    dEntry = new DirectoryEntry(ldapUrl, null, null, 
                AuthenticationTypes.SecureSocketsLayer | AuthenticationTypes.Secure); 
    DirectorySearcher search = new DirectorySearcher(dEntry);
    search.Filter = "((objectClass=*))";    
    search.Filter = searchQuery;
    SearchResultCollection scl = search.FindAll();

    That's usually a certificate issue.

    Check the system event log on the client machine and see if there are any ssl/schannel errors.

    In case these errors are being suppressed: Make sure that the certificate matches everything you're expecting. Host name, expiration, etc.

    I suggest you use Softtera Ldap software to test connections to Ldap before trying with the code. It will give you detailed error.
