Right, but the local "create/modify user script" at the site might get
confused. As I said before, I'll make it a runtime option (defaulting to

What's wrong with "kadmin add user" now ? Is there anything else someone
want to add when creating a user ?

I take your word for it. But I would feel much better if some other ldap
literate person spoke up and said what you said was right.

This is not really related to samba but...

The entry look something like this, X509:<I>CN=Issuer<S>CN=Subject, so yes,
its both names (issuer, subject).

I want to store the certificate as an alternative to altSecurityMumble
because for certain certificate you might not want to trust the CA, but the
smartcard with the certificate is just fine.
I could use the userCertificate, but should I really use that for acccess
control checks ?
So there are four ways I want to do check if the certificate is allowed to
use this principal.
match subject + issuer
match whole certificate
match some site specific function mapping cert to principal via plugin
