wildcards for principals when generating ssh certificate

[Jiri B]

Hi,

is it possible to have a wildcard in principals when generating
user certificate?

ssh-keygen(1) states:

  ssh-keygen -s ca_key -I key_id -h -n host.domain user_key.pub

I mean something like this:

  ssh-keygen -s ca_key -I key_id -h -n webapp*.domain user_key.pub

Thanks for clarification.
