Importing and using non-self-signed PGP keys

[Schwarz, Konrad]

Hi,

my organization issued to me a public/private PGP keypair
that is not self signed.

I managed to import these keys into GPG 1.4.19 with the
--allow-non-selfsigned-uid flag, as described in
https://www.gnupg.org/gph/en/pgp2x/x58.html

How can I self-sign the new uid in GPG, or,
for that matter, do anything else with it?

I keep on getting the errors `User ID ... is
not self-signed.  Unable to sign.'

Regards

Konrad
