[Samba] finger print for samba-pubkey.asc

[Richard Seegmiller]

When I run

gpg --verify samba-2.2.7a.tar.asc

I get the following output:
gpg: Signature made Fri Dec 13 12:23:00 2002 CST using DSA key ID 2F87AF6F
gpg: Good signature from "Samba Distribution Verification Key
<samba-bugs at samba.org>"
WARNING: This key is not certified with a trusted signature!
           There is no indication that the signature belongs to the owner.
Primary key fingerprint: ...

Where may I find a trusted authority for the fingerprint of the samba
public key found at (for example)
  http://us3.samba.org/samba/ftp/samba-pubkey.asc ?

Thanks
Richard
