Plug and Play Weirdness, PnP with AAA Configs in Scripts (Cisco SR 688994803)

Anyone noticing DNA-C odd handling on AAA commands within the PNP config push (DNA-C 1.3.3.x)? Examples:

 

Provision --> Devices --> Plug and Plug Devices -->  Device Name --> Configuration --> Template (preview)

 

!
aaa new-model
!
aaa authentication login ISE-AUTHENTICATE group ISE-TACACS local
aaa authentication login LOCAL-AUTHENTICATE local group ISE-TACACS
aaa authorization console
aaa authorization commands 1 ISE-AUTHORIZE group ISE-TACACS local
aaa authorization commands 15 ISE-AUTHORIZE group ISE-TACACS local
aaa authorization commands 15 LOCAL-AUTHORIZE local group ISE-TACACS
aaa accounting commands 1 default stop-only group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
!
line con 0
exec-timeout 60 0
privilege level 15
authorization exec LOCAL-AUTHORIZE
logging synchronous
login authentication LOCAL-AUTHENTICATE
!
line vty 0 15
exec-timeout 60 0
privilege level 15
authorization commands 15 ISE-AUTHORIZE
logging synchronous
login authentication ISE-AUTHENTICATE
transport input ssh
!

What makes it into the configs:

 

aaa new-model 

aaa authentication login ISE-AUTHENTICATE group ISE-TACACS local
aaa authentication login LOCAL-AUTHENTICATE local group ISE-TACACS
aaa authorization console
aaa accounting commands 1 default stop-only group tacacs+
aaa accounting commands 15 default start-stop group tacacs+

 

line vty 0 4
access-class REMOTE_ALLOW in
exec-timeout 60 0
privilege level 15
authorization exec LOCAL-AUTHORIZE
logging synchronous
login authentication LOCAL-AUTHENTICATE
line vty 5 15
exec-timeout 60 0
privilege level 15
authorization exec LOCAL-AUTHORIZE
logging synchronous
login authentication LOCAL-AUTHENTICATE

 

Console's AUTH commands make it into VTY and authorization commands dropped global AAA configurations

Modified his script a bit, but led the right direction (APIC-EM issues often surface on DNA-C):

event timer countdown time 180
action 1.0 cli command "enable"
action 1.3 cli command "config t"
