PnP AAA username format

When editing the device details of a pre-provisioned switch which has AAA authorization command in it. The template asked to provide credentials. The username is suffixed '.gen'. APIC-EM complains that this is an invalid username due to the presence of the full-stop character.
Have tried enclosing it in quotes, double-quotes, guessing at escape characters which might work, but unable to find any combination which will take the username.

If you have the ".gen" as the first username in the APIC-EM discovery, then it will be used by default to discover the device.

You can use my EEM script workaround to handle the "aaa authorisation" issue.

Not perfect, but would allow you to progress until we fix the pnp username.
