When using the FTPS adapter to connect to an FTP site with SSL/TLS, I'm getting the following error:
The server name in the server certificate does not match with the name of the physical server. Make sure you provide the right server name. ".
Is there any way to override this behavior so that BizTalk will accept and use the certificate? I have the public certificate loaded into the personal store and the trusted store of the send handler user.
After doing some more research, I've come to the conclusion that this is a limitation of the Microsoft FTPS adapter. The only way to resolve this issue is to get certificates where the common name matches the DNS name, or to use a third-party FTPS adapter like the /n FTPS adapter.

I am using .NET 6 to try to make to work the default gRPC service that is created when I create a new gRPC project for ASP.
To test if I can connect to the service, I use grpcui.
I can connect when I don't use certificates, connecting to the http address, but when I try to use a certificate, using the https address, I get the error:
Cannot validate certificate for x.x.x.x because it doesn't contain any IP SANs.
I guess that is because I don't create the server certificate in the correct way, because I have to set the IP in the field SAN, but I don't know how.
What I did it is to set as CN the IP of the server, but it seems that this is not the correct place to set the IP.
So I would like to know what is SAN and how I could create the certificates with this field.
My application needs to access files from a remote FTPS or SFTP server depending on what my app user wants to connect to. I need to be able to access file content in a folder or create a folder.
1) What login properties differ for an FTPS and SFTP server that a user must enter?
2) Is there any way I can detect if it is an SFTP or FTPS server?
SFTP doesn't have any authentication. SFTP protocol is supposed to be used over SSH connection, thus it relies on SSH for authentication. So all authentication mechanisms of SSH apply. The list of such mechanisms is extensive - you can authenticate using password, a private key ("public-key authentication"), X.509 certificate (not a popular option), keyboard-interactive (challenge-response) dialog, also via GSS-API you can use Kerberos and possibly other mechanisms. FTPS as FTP-over-TLS can also use various mechanisms. FTP uses username/password by default, but potentially one can implement some tricky mechanisms using SITE command. TLS protocol includes client-side authentication using X.509 certificates, pre-shared symmetric keys, plain PKI keys, OpenPGP keys.
SFTP and FTP/FTPS are completely different protocols. Servers run on different ports. If you want to implement protocol autodetection, you can try the following: connect to the server, and if it sends a welcome SSH message within 200-500 ms, you know that it's an SSH (and potentially SFTP) server. If it sends a welcome FTP message, it's an FTP server (this includes explicit TLS mode of FTPS). If it sends nothing, then it can be a TLS server and you can have implicit FTPS over this connection.
How can I specify detailed proxy settings in TweetSharp? By this I mean in addition to the server name, details like Port, Username, Password etc? As of now the only parameter, is
Dim X as New TwitterService(Key,Secret)
X.Proxy = "abcd"
Which accepts only a string, which I assume is the server name / IP Address.
My app is behind a corporate firewall and the proxy requires authentication and uses a custom port. Any ideas?
As I was completely unable to specify the authentication details for the proxy server, I was forced to come up with my own workaround. I installed ccproxy on the server, and had it cascade the authentication to the other proxy server.
This is working well as of now.
I want to send a request to HTTPS adapter through BizTalk server 2009. My BizTalk adapter is dynamic and it's takes configuration details from database instead of directly mentioning it on server.
I have installed X509 certificate in my browser and imported it in MMC.
I am getting following error in my BizTalk
A message sent to adapter "HTTP" on send port "sndHL7" with URI "https://xxxxxxxxx/imm/test (https://xxxxxxxxxxxxx/imm/test)" is suspended.
Error details: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel
I searched for this error, but every where I got following response only :
Error: – Details: “The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
Solution: The error message normally occurs if the client certificate is not configured correctly. You should check that you have configured your client certificate in certificate store under BizTalk service account that hosts the HTTP adapter.
I am not getting how to configure that certificate in proper certificate store. I have 3 files wih extension .cer, .cer and .pfx. The file with extension .pfx requires password to install it in any store.
Also, how to configure certificate under BizTalk service Account? Should I select "Service Account" while adding snap in in MMC and then select BizTalk service from the list of services.
I don't know about biztalk but if you are presenting a cert you need the associated private key. A cert is like a photo ID. It is hard to forge, but it still doesn't prove your identity unless you can present your face for someone to compare with the ID. Assuming the file extensions match the actual format of the files, the cer files are either DER, BER or PEM encoded certificates without the private key. So you need the pfx file. So if the proposed solution from the error message is correct, you need to find that password and install the certificate and private key from the PFX file into the store.
The two .cer files must be the root authority and server certificates and you must trust them.so you need to place them in your LOCAL MACHINE- Trusted Root Certification store. (use MMC)
Now the .pfx file will have the client authentication certificate that you will be passing into get authenticated. Import this certificate to LOCAL MACHINE,Personal (or MY certificate store if using command line) check private key as exportable.
Now allow BizTalk service account access to the private key of this certificate.
MMC use add snap in and add local machine.
select the client certificate in Personal right click- AllTasks- Manage private keys. Now add your BizTalk service account as a user and give access.
Or else use winhttpcertcfg tool in command line
I need to install a certificate for encryption (replication) between an external vendor and my company.
I cannot get a third party certificate for the FQDN of my server because the net part of that does not match a domain that we own (ie my FQDN is sqlservername.company.root.net but we don't own a domain called company.root.net.). We do own mycompany.com, so I got sqlserver.mycompany.com on the cert and have a DNS entry to alias sqlserver.mycompany.com to sqlservername.company.root.net.
I cannot use a self generated cert since the vendor needs to trust the cert authority.
I have a cert that I have purchased and installed, but SQL Server won't see it since the FQDN doesn't match.
I tried installing it by putting the thumbprint of the cert into the registry directly, but then SQL server won't start with the following errors:
The server could not load the certificate it needs to initiate an SSL connection. It returned the following error: 0x8009030e. Check certificates to make sure they are valid.
Unable to load user-specified certificate [Cert Hash(sha1) "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"]. The server will not accept a connection. You should verify that the certificate is correctly installed. See "Configuring Certificate for Use by SSL" in Books Online.
(where the x's above match the thumbprint of the cert without spaces)
TDSSNIClient initialization failed with error 0x80092004, status code 0x80. Reason: Unable to initialize SSL support. Cannot find object or property.
What do I need to do differently to get this working?
You need to use MMC to install your certificate in the certificate store and then use the SQL Server Configuration Manager to link the certificate to your SQL Server service. See https://support.microsoft.com/en-us/help/316898/how-to-enable-ssl-encryption-for-an-instance-of-sql-server-by-using-mi
Then, make sure that the service-account running you SQL Server service has full permission on the certificate. In MMC, right-click on the certificate, select Manage private key, and then grant full access to the service-account running you SQL Server.
You should restart your SQL Server for the changes to take effect.
Before anything else, you must install the certificate in the Windows certificate truststore.
Did you do that?
The error
You should verify that the certificate
is correctly installed
seems to indicate you did not do this.
I was expecting that the hostname verification would be configurable but from here SSL in MS-SQL2008 r2 it seems as an absolute requirement.
To be honest I am not sure if the trick you did with the DNS entry will work.
It seems that some tweeking works for cluster installations ssl for cluster installations
In your case, may be you should have bought the certificate using the IP as subject name and use DNS to resolve to the FQDN you say.
But of course this implies use of a static IP and most likely it would not be feasible as well anyway.....
