This case is for documenting support for TLS v1.2, AES256 and Kerberos v5 in CA PAM 3.4.X
CA Privileged Access Manager v 3.4.X
According to the following link
TLS v1.2 and AES256 are supported. Also, Kerberos v5 is supported as well.
Basically internally klist shows the client is v5
root@<servername>:~# klist -V
Kerberos 5 version 1.15
Which shows PAM is using KRB 5
