Provision error on Dnac

[Ciro G Mele]

Good afternoon
I can ask you a question, can someone help me?
When I want to provision the changes this error appears, does anyone know the solution without having to open a ticket in tac

Thanks a lot

I can't tell just from this piece of information

but the section concerns modifying the AAA configuration!
as a result of this modification it can mean the DNS service account at some time does not have the rights to make all necessary modifications
=> try to provision with "configuration preview" to have DNA display what config lines are added/removed/changed
inspect this preview for lockout of the DNA service account during the process

Is TACACS configuration getting configured during this workflow? 

If so, DNA center might lose access to authenticate into DNA Center via TACACS once this configuration is pushed.
