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
https://techdocs.broadcom.com/us/en/symantec-security-software/identity-security/privileged-access-manager/3-4-3/implementing/configure-policies-to-provision-user-access-to-devices-and-applications/configure-devices/set-up-access-to-a-target-device/access-methods.html
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
apt list | grep krb
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
krb5-config/now 2.6 all [installed,local]

libkrb5-3/now 1.15-1+deb9u1 amd64 [installed,local]

Which shows PAM is using KRB 5
