New encription method to use with Kerberos client keytabs in communication with modern Windows Servers

See this idea on ideas.ibm.com

If You need to start secured communication from DP GW (or ACE) to modern Windows Servers normally You could use Kerberos client keytabs. After recent changes in Kerberos / Netbios protocols Microsoft "say goodby" to last availble encription method RC4 HMAC NT (DES never was available in any modern Windows Servers like Windows Server 2012 and newer). So currently there is no way to use secured communication (basic authentication not count as "secure") using "service" accounts in cases were DP GW initiate communication.

    Hi - We already support algorithms other than RC4, like AES. It's possible that you may have run into a variant of the issue introduced by the Microsoft KDC patch. Also separate from what algorithms we support is what key(s) are put into the keytab and whether the keytab was correctly created for each change in KDC configuration. Please see the similar conversation here https://integration-development.ideas.ibm.com/ideas/APICONN-I-705

    I would suggest re-trying after addressing the Microsoft KDC patch and validate if there are any algorithm-dependency aspect to the issue.
