A third-party team is about to implement Cloudera hadoop in our existing AD and they have decided to implement it using RC4 encryption. For this to occur, I think we might need to allow this type of encryption for Kerberos using GPO, since by default it is not supported. (I am not a security guy, correct me if I am wrong!).

Has anyone ever tried enabling this encryption using GPO "Network security: Configure encryption types allowed for Kerberos" ? any compatibility issues with clients? Errors? 

I am open to any ideas toward this.
